A Comact Microstrip Patch Antenna for Wireless Communication

A single feed compact rectangular microstrip antenna is presented in this paper. A triangular slot is introduced at the upper edge of the patch to reduce the resonant frequency. A small piece of triangular patch is added within the area of the triangular slot to improve the gain bandwidth performance of the antenna. The antenna size has been reduced by 46.2% when compared to a conventional square microstrip patch antenna with a maximum of 160MHz bandwidth and i27:36dB return loss. The characteristics of the designed structure are investigated by using MoM based electromagnetic solver, IE3D. An extensive analysis of the return loss, radiation pattern, gain and e-ciency of the proposed antenna is shown in this paper. The simple conflguration and low proflle nature of the proposed antenna leads to easy fabrication and make it suitable for the
