| Abstract: | Using the circular loop antenna as a feed source, the exoteric resonance cavity as reflect object, a strongly-directional circular backfire antenna was designed. The antenna＇s working frequency was 2 GHz, and the input impedance was matched. The antenna was tested and studied. It had excellent applied performance： high gain, large ratio front and back, low power of the adjacency beam, large bandwidth, easy feed in power, and so on. |
