Design and Simulation of Airborne Circular Omni-Directional Slot Antenna

Abstract:

The airborne omni-directional antenna must not only satisfy the indicators of omni-directional horizontal requirements, but also have conformal shape with the surface of airplane. The common monopole antenna and microstrip antenna can not meet the above requirements. Under the background of the airborne antenna miniaturization and conformal demand, this article designs a kind of airborne circular slot antenna. The structure of the antenna is simple, which meets pattern VSWR < 1.4 bandwidth of 350 MHz to 376 MHz and meets pattern VSWR < 2 bandwidth of 338 MHz to 438 MHz .Its maximum gain within the operating frequency range can be 4.205 dB .
