Abstract
The development of communication engineering with integration technology demands size reduction of low frequency antennas as an important design perspective. In this work, a microstrip patch antenna with a c-shaped-slot implemented on a relatively thin substrate (about 0.03 λ0), and (εr = 2.2) is shown to bring a size reduction an ordinary microstrip patch antenna for the same resonant frequency. However size reduction comes at the cost of bandwidth and the gain which are then enhanced to a good level by using one pair of transmission-lines-feed and annular ring slots. The composite effect of integrating these techniques offers a low profile, broadband, and multi-band functionality. The proposed antenna is designed to function in the WIMAX (3.27–3.4GHz and 6.9–7.8GHz) bands and it is shown to bring a size reduction of about 40% compared to an ordinary microstrip patch antenna for the same resonant frequency.
