Wideband microstrip antennas for cars and commercial vehicle modern communication system

Abstract

The basic work is directed at designing an antenna suitable for car and commercial vehicle modem communication system. One of the disadvantages of the microstrip patch antenna is its narrow bandwidth. This limitation can be overcome by modifying the conventional microstrip patch antenna. Various methods have been surveyed and this lead to the conclusion that no proper design technique has been published yet, All of the published papers and books provide the conceptual design but not the exact technical design steps. A design technique has been proposed in this project that will enhance the microstrip antenna. This technique has removed the guesswork normally associated with previous wideband ; microstrip patch antennas design and it consistently achieving at least 10-15% antenna bandwidth.
