Abstract

In wireless communication, PIFA is the best candidate for mobile antenna design. In this paper single feed compact PIFA for wireless communication is presented. We have used mainly two techniques to reduce physical size of the antenna. First, we inserted U slot within the antenna surface. Second, a capacitive plate is inserted between radiating surface and the ground plane [2]. By changing the gap between radiating surface and the ground plane we have got change in results. By inserting more than one slot we got different result but by doing comparative study we came to know that good result can be achieved by inserting one slot with appropriate dimensions. Triple band PIFA antenna can be achieved by these techniques. The reduced size and less height of the substrate allow design to be compatible with wireless applications. Here the simulation results match with the current market requirements. The simulation is done in HFSS Software.

Abstract

This paper proposes Microstrip Rectangular Patch Antenna in which metamaterial properties applied at ground Plane. The paper also analyzed the performance of Microstrip Patch Antenna with and1 without using the metamaterial structure at 10 GHz. The works mainly include Metamaterial as Defected ground plane. The Open Slot Split Ring resonator is used as metamaterial. The effective permeability parameters are retrieved from s parameters for unit cell Split Ring Resonator, revealing the presence of magnetic resonances around resonance frequency 10 GHz. All antenna parameters such as Return Loss, Gain, and Band width were checked. The main focus of this paper was to check the effect of metamaterial so that Patch antenna used for multi band operation.
