Perturbed hexagonal antenna at 14.7 GHz

Abstract

This paper represents a high-gain, single resonance microstrip patch antenna which operates at 14.70 GHz. Measurement result of electric field phi-polarized gain is 10.72 dB. There is an alternative design with four rectangular slots at 19.60 GHz. This antenna has compact structure thereby achieving size benefits over previously published works in literature. As a reason of large slitted structure the antenna manufactured easily and works well at high frequencies with more than 10 dB gain.
