| Abstract | ||
| A new reduced size single probe fed microstrip patch antenna with irregular slits has been presented to be used as a receiving antenna for Global Positioning Systems (GPS) integrated with cellular handheld mobile wireless systems. The proposed design is based on the nearly square microstrip patch antenna with two pairs of orthogonal slits cut from the edge. It has been found that this antenna offers further reduction in size with good radiation properties required for GPS system. The resulting circular polarization bandwidth (with axial ratio ≤ 3 dB) has been found to meet that required for this application. The proposed antenna possesses an average gain of 4.5 dB overall the GPS L1 operation. | ||
