Abstract
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.
