Design and Simulation of the Air-Gap L-Shaped Feeding Arc Slot Antenna

Abstract

In the efforts to improve the capability of duty service and contingency-handing of informational system and deal with the communications security of helicopter, according to the request of the airborne electromagnetic equipment miniaturization and conformal, design of an air-gap L-shaped feeding arc slot antenna. This antenna is an omnidirectional antenna, its profile height under 0.03 working wavelength, the size under 0.5 working wavelength and the transmission gain exceed 3dB.
