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

A compact slotted patch antenna with single layer, single feed is simulated in this paper. By cutting two unequal slots at the upper right and lower left corner from the conventional microstrip patch antenna, resonant frequency has been reduced drastically compared to a conventional microstrip patch antenna and also simulated antenna size has been reduced by 34.22% with an increased frequency ratio.

A single layer, single feed compact slotted patch antenna is thoroughly simulated in this paper. Resonant frequency has been reduced drastically by cutting two different slots. The first one is the combinations of two triangular and another rectangular slot at the upper right corner and rest is bilateral triangle at the lower left corner from the conventional microstrip patch antenna.

A single layer, single feed compact slotted patch antenna suitable for dual-band operations is thoroughly simulated in this paper. Patch antenna is basically a low cost, light weight, medium gain and narrowband antenna and suited for short-range microwave application such as a feeding element for other antennas and in research institutes as a reference antenna, it can also be used at output of signal conducting circuit for receiving signals from MEMS. By loading properly arranged slots on a rectangular microstrip patch, dual frequency and broadband operations of a single feed rectangular patch is achieved to increase bandwidth performance of the antenna. The impedance bandwidths of 562.85 MHz with return loss -28.64 dB and 1.17 GHz with return loss -43.40 dB are obtained in the proposed design. And simulated antenna size has been reduced by 59.07% with an increased frequency ratio when compared to a conventional microstrip patch antenna. The characteristics of the designed structure are investigated by using MoM based electromagnetic solver, IE3D. The simple configuration and low profile nature of the proposed antenna leads to easy fabrication and make it suitable for the applications in microwave communication system.
