A novel technique for the bandwidth enhancement of conventional proximity coupled equilateral triangular microstrip antenna is proposed. When a notch-T shaped slot loaded over the patch, the bandwidth of the designed antenna was increased by more than eight times without affecting its radiation performance. The performance of the designed antenna was analyzed in term of bandwidth, return loss and radiation pattern. The proposed antenna will be useful for IMT (International Mobile Communication), WLAN (Wireless Local Area Network) and SAR (Synthetic Aperture Radar).
