| Abstract: | The half-loop antenna is one of the vehicular HF antenna. The base modeling of half-loop antenna is implemented by using HFSS simulation software,then the reflection loss curve and the antenna patterns of four frequencies are simulated and the influence of different frequencies on the direction patterns is analyzed. The communication performance of the half- loop antenna and the 3- loop antenna is compared and analyzed by test values. The experimental results show that the half- loop antenna can effectively overcome the blind area in HF communication. |
