Core Product Features: Perfect Integration of Compact Design and Efficient Performance

1. Electrical Characteristics: Precise Low-Frequency Coverage, Stable Signal with No Dead Angles

• Wide Low-Frequency Adaptation：Operating frequency range locked at 800-2200Hz, designed exclusively for low-frequency short-range wireless communication scenarios. It is compatible with industrial sensors (e.g., vibration, pressure sensors), low-frequency wireless access control, security alarm systems, etc., meeting the requirements for stability and penetration in low-frequency signal transmission (low-frequency signals have stronger penetration in complex environments, suitable for industrial workshops with many obstacles or building interiors).
• 360° Omnidirectional Radiation：Adopts 360º omnidirectional radiation technology, allowing signals to spread evenly in all directions. No precise alignment with the receiver is required, solving the "angle dependence" problem of directional antennas—even in equipment-dense workshops or multi-wall buildings, it ensures stable communication for multi-node devices (e.g., multiple sensors, access control terminals).
• Low-Loss Signal Transmission：Equipped with an RG174 low-loss coaxial cable (length: 1000mm/1m) with stable impedance (50Ω, standard impedance for low-frequency devices), which effectively reduces signal attenuation during transmission. It is especially suitable for scenarios where the device and antenna need to maintain a certain distance (e.g., sensors installed on robotic arms, antennas fixed on control cabinet surfaces); comes with an SMA male jack (inner thread + inner pin)—the precision connector firmly mates with SMA female sockets of most low-frequency devices, avoiding signal fluctuations caused by poor contact.

2. Mechanical Characteristics: External Patch Design, Adaptable to Space-Constrained Scenarios

• Ultra-Thin & Compact Shape：As an external patch antenna, it has dimensions of only 116mm×21.6mm and a thickness of less than 5mm (typical thickness of patch antennas). It can be directly pasted or fixed on flat surfaces (e.g., device casings, walls, control cabinet doors), without occupying three-dimensional space—especially suitable for small devices (e.g., handheld terminals, portable detectors) or narrow installation environments (e.g., inside equipment, dense industrial cabinets).
• Lightweight & Flexible Installation：Weighing only 18g (about the weight of 2 coins), it exerts no load pressure on the carrier after installation; supports two fixing methods: pasting (with self-adhesive backing) or screw fixing (reserved mounting holes), both of which can firmly fit flat surfaces, meeting the needs of different scenarios (e.g., pasting for temporary deployment, screws for long-term fixation).
• Durable Structural Design：The antenna body uses FR-4 epoxy glass cloth substrate (a common material for patch antennas), which has both insulation and mechanical strength, and can resist slight impact and vibration; the outer layer of the RG174 cable is wrapped in oil-resistant PVC material, suitable for industrial workshops and other environments that may come into contact with oil, extending the service life.

3. Environmental Characteristics: Compliant & Eco-Friendly, Adaptable to Multi-Working Conditions

• Dual International Environmental Certifications：Strictly complies with RoHS & REACH regulations, containing no harmful substances such as lead and mercury. It can be safely used in food processing workshops, medical equipment supporting, household electronics and other scenarios with high environmental requirements, avoiding procurement restrictions due to non-compliance.
• Wide Temperature Range & Anti-Interference：The optimized circuit design supports an operating temperature range of -30~+70℃, enabling stable operation in industrial workshops (high temperature in summer), outdoor cabinets (low temperature in winter), etc.; the patch structure itself has certain anti-electromagnetic interference capabilities, reducing interference from surrounding equipment to low-frequency signals.

Core Advantages: Three Breakthroughs for Low-Frequency Communication Scenarios

• "Space-Friendly" Design：The ultra-thin patch shape (116×21.6mm) solves the problem of "large size and difficult installation" of traditional antennas, especially suitable for miniaturized devices (e.g., portable low-frequency detectors) and densely laid scenarios (e.g., production line sensor clusters).
• "Omnidirectional Low-Frequency Coverage"：The combination of 360° radiation and 800-2200Hz low-frequency band ensures no signal dead angles, while leveraging the strong penetration of low frequencies to maintain stable communication in environments with multiple walls and equipment obstructions (e.g., warehouses, basements).
• "Multi-Scenario Compatible Installation"：Supports both pasting and screw fixing methods; the 1m RG174 cable can flexibly adjust the distance between the antenna and the device, adapting to different needs such as temporary deployment (e.g., exhibition equipment) and long-term fixation (e.g., workshop production lines).

Multi-Industry Application Scenarios: Focusing on Core Needs of Low-Frequency Communication

• Industrial Sensing & ControlCompatible with low-frequency vibration sensors, pressure sensors, and temperature-humidity sensors in workshops. The patch antenna is pasted on equipment casings or control cabinet surfaces, and the 1m cable connects to sensor modules. 360° omnidirectional radiation ensures stable transmission of sensor data (e.g., machine tool vibration frequency, pipeline pressure) to industrial gateways; the low-frequency band penetrates machine casings and other obstacles, avoiding signal interruption that affects production monitoring.
• Low-Frequency Security & Access Control SystemsUsed in wireless access control card readers, low-frequency electronic locks, and security alarm terminals. The antenna is pasted on door frames, walls, and other flat surfaces. The 800-2200Hz band adapts to low-frequency signals of access control systems (e.g., ID card identification signals); omnidirectional radiation allows cardholders to sense without aligning with the reader within a certain range (e.g., 1-3 meters in front of the door), improving usability; compliance meets environmental requirements of public places such as shopping malls and schools.
• Portable Detection EquipmentPaired with handheld low-frequency detectors (e.g., metal detectors, underground pipeline locators), the antenna is fixed on the back of the device with adhesive. The ultra-thin design does not affect the grip feel, and the 1m cable is routed hidden without interfering with operation. Low-frequency coverage and low-loss transmission ensure the device can accurately receive/transmit detection signals in complex environments such as outdoors and building interiors.
• Smart Home & IoTApplied to household low-frequency sensors (e.g., water leak detectors, door/window magnetic sensors), the patch antenna is pasted on walls or furniture surfaces, with a compact shape integrating into the home environment. 360° radiation covers indoor spaces, ensuring stable communication between sensors and smart home gateways, avoiding missed alarms (e.g., undetected water leaks) due to weak signals.
• Agriculture & Environmental MonitoringAdapted to outdoor low-frequency soil moisture sensors and water quality monitoring terminals, the antenna is fixed on the metal casing of monitoring equipment with screws. The wide temperature range resists day-night temperature differences in fields (-10~+60℃); low-frequency signals penetrate obstacles such as soil and vegetation, ensuring stable upload of monitoring data (e.g., soil conductivity, water turbidity) to the management platform.
