Gain-Enhanced of Triangular Microstrip Antenna Using Artificial Magnetic Conductor

Abstract

The design of a microstrip antenna based on artificial magnetic conductor is presented in this paper. The antenna is composed of a triangular microstrip antenna and with an artificial magnetic conductor made by an uniplanar compact electromagnetic band gap structure. The height of microstrip antenna from the plane of the artificial magnetic conductor is $0.083\lambda$. Due to in-phase characteristics, the antenna radiates only in half space with the use of artificial magnetic conductor structure. The size of the antenna is further reduced to meet the requirements of the small electric antenna. The gain is greater than 7.8dB.
