The Loop Antenna is usually applied to the fixed communication station as well as the HF vehicular communication devices. The antenna adopts the  techniques of the magnetic loop antenna, which makes the inner small loop coupled and excited the large loop outside by power feed of the small loop. On the condition of resonance, the large loop could radiate power.

The antenna array is insulated with the antenna foundation. The design isolates multiple noises (includes the noise of friction by the electric appliance and machine), purifies the background of the channel distinctly, and enhances the SNR of signal receiving. The antenna has no short distance dead zone, while the longest communication distance is 800km. The antenna could be applient with antenna tuner for achieving fast tuning at different point within the frequency range and achieving the perfect communication effect.
The antenna is composed of the large loop, the small loop, the antenna matching device, the antenna tuner and the antenna foundation, which features simple structure, convenient installation and small occupation. The communication effect of the loop antenna is basically equivalent to the 44m dipole antenna.
