Design, Fabrication and Performance Analysis of Microstrip Patch Antennas for Wireless Applications

Wireless communications has been developed widely and rapidly in the modern world especially during the last two decades. The future development of the personal communication devices will aim to provide image, speech and data communications at any time, and anywhere around the world. This indicates that the future communication terminal antennas must meet the requirements of multi-band or wideband operations to sufficiently cover the possible operating bands. However, the difficulty of antenna design increases when the number of operating frequency bands increases within a single antenna. The aim is to study and design various rectangular microstrip patch antennas for wireless communication systems and study the effect of various antenna parameters like patch length (L), patch width (W), substrate relative dielectric constant, substrate thickness etc. Here CPW feed and microstrip line feed methods have been used to excite the patch antenna.
