Spring antennas, also known as helical antennas, are a type of antenna commonly used in wireless communication systems, including Wi-Fi, Bluetooth, and cellular networks. Named for their helical spring-like shape, they are designed to increase the antenna’s efficiency and reduce its size.

The helical shape of the spring antenna offers several advantages over other types of antennas. This shape allows for more turns of copper wire in less physical space, which increases the efficiency of the antenna, more electrical energy is converted to radio waves and less is lost as heat.

The radiation pattern of a spring antenna depends on its design parameters such as number of turns, spacing between turns, and coil diameter.
