An improved multi-band broadband patch antenna with low dielectric constant (ε r = 1.03) suitable for personal communication services is presented. The improved antenna is obtained by introducing an angular displacement to the probe feed position. This offset of the probe from the x-axis also results in an additional antenna mode. Thus enabling its application for satellite TV communication in C-Band. The impedance bandwidth, determined from the 10-dB return loss, is much greater than that of the same antenna without angular displacement.
