Abstract :
A broadband fractal slot coupled stacked microstrip antenna is presented. Third order fractal slots are used, to improve the antenna bandwidth. The antenna resonates at the center frequency of 1.5GHz and offers 30% bandwidth for a return loss criterion of 10dB. The introduction of fractal slot also leads to antenna miniaturization. The proposed configuration is fabricated and characterized for gain, return loss and radiation patterns. While the measured peak gain of the fractal slot coupled antenna configuration is 8 dB at the center frequency, an average gain of 7dB is measured over the band.
