Design of Dual Band Patch Antenna Array : A Survey

Abstract

Antenna array is a systematic arrangement of radio waves working together. Antenna array deals with the design of dual band patch antenna array. Designing should be in such a way that it increases the efficiency and gain of a microstrip patch antenna without any change in the whole structure. Frequency range of antenna operates between 3.1 GHz and 12 GHz. In same frequency band of two coplanar microstrip antennas mutual coupling introduced and split-ring resonators (SRR) reduce mutual coupling between two microstrip antennas. The split ring antenna array gives better performance qualitatively and used for wireless multiple input and multiple output applications. Antenna array is useful in wireless applications such as long term evaluation, Wimax.
