    Analysis and Design of A Compact Microstrip Patch Antenna With Enhanced Bandwidth and Gain for Wireless Local Area Network (Wlan) Communications
    (Addis Ababa University, 2010-07) Debo, Feyisa; Abdo, Mohammed (PhD)
    In this thesis, the compact microstrip patch antennas in stacked configuration have been proposed. The microstrip patch antenna structure consists of a square patch with four equal u-shape on four sides of each patches. These structures provide an optimized patch area resulting in a substantial reduction in size compared to a typical microstrip square patch designed at the same frequency of operation. The characteristics of the antenna are obtained in terms of return loss, gain, radiation pattern and bandwidth and are compared with the conventional microstrip patch. The stacked configuration enhances both gain and bandwidth of the microstrip patch antenna at 2.45GHZ operating frequency. A size reduction of 70% is obtained along width 24.4dB gain and 6.6519GHZ bandwidth. The empire software is used to obtain the optimized performance of the proposed antenna. This antenna is found to be suitable for WLAN communications. Key Words: size reduction, stacked microstrip patch antenna, gain, bandwidth.
