In the recent years the development in communication systems requires the development of low cost, minimal weight, low profile antennas that are capable of maintaining high performance over a wide spectrum of frequency. This technological trend has focused much effort into the design of a Microstrip patch antenna. However, the difficult of antenna design increases when the number of operating frequency band increase. In additional, for miniaturization the wireless communication system, the antenna must also be small enough to be placed inside the system. In order to transmit and receive more information large bandwidth are required, and bandwidth enhancement is currently a popular research area. The aim of this thesis is to design a rectangular microstrip path antenna for global WLAN systems and study the effect of various antenna parameters such as the performance of the antenna in term of radiation pattern Directivity, gain, bandwidth, VSWR, return loss and, far-field etc. here line feed method was used to exited the patch antenna. The First antenna was designed to operate at a resonant frequency of 2.45GHz dielectric substrate (Rogers RT5870) with relative permittivity (=2.33) and thickness of 0.787mm, for applications such as IEEE 802.11 Wi-Fi, IEEE 802.15.1 Bluetooth, IEEE 802.15.4 ZigBee, wireless USB, microwave oven, codeless phone etc. The proposed antennas have been design using Matlab, modeled and simulated by using computer simulation technology (CST) micro studio. The simulation results of designed antennas indicate that the proposed antenna fulfils the excellent requirements and characteristics for various frequency bands and showing the good radiation patterns and characteristics in the interested WLAN communication. INTRODUCTION The field of wireless communications has been growing since the invention of portable mobile phones some decades ago. The success of the second-generation (2G) cellular communication services leads to the development of wideband third-generation (3G) and fourth-generation (4G) cellular phones and other wireless products and services, including wireless LAN, Bluetooth etc. The devices using these communication services are mostly portable and run on batteries. That means, components in these devices should be of small size and consume low power. Moreover, some wireless devices are required to support multiple wireless services and very high data rate. As an antenna is the crucial part of any wireless device, the development of highly efficient, low-profile, small-size, multi-band and wide band antennas that can be made embedded into wireless products are very much demanded.
