Product Description

 

Product Description

Spiral antenna is one of the most commonly used circularly polarized antennas in engineering, which can achieve left or right rotation by changing the direction of the spiral. Its suitable operating frequency is between 200-5000MHz. Its gain is within 3-12dB. Especially at the low end of the frequency, due to wavelength, spiral antennas are smaller in size than other antennas.
