Abstract

Recently, wireless communication systems have developed rapidly and have become more mobile and small. This necessarily requires the adequacy of its design. The materials used should be as much as possible small and at a lower cost. So low cost with reduced volume and low weight are some of the major challenges that must be faced by the designer of modern telecommunications equipment. The microstrip planar antenna is an attraction and the most crucial component used in mobile systems, and its miniaturization is one of the research challenges. This chapter focuses on the concept of miniature reconfigurable antennas by presenting and discussing the state of art with contributions in designing reconfigurable miniature printed antennas.

Microstrip Patch Antennas

Introduction

In its most basic form, a microstrip patch antenna consists of a radiator mounted on an FR4 substrate associated to a ground plane as shown in Figure 1 (Carver, 1981).

The different parameters of the antenna are as follows: L is the length of the patch, w is the width; h is the thickness of substrate and t is the metallization thickness of the patch.

The patch is generally square, rectangular, circular, triangular, and elliptical or other shapes as illustrated in Figure 2. Square, rectangular, and circular are the most celebrated because of ease of analysis, fabrication, and their attractive radiation characteristics, especially low cross-polarization radiation (Bahl, 1980; Wheeler, 1959; Abla, 2010).
