| Abstract: | As a part of the modernization of GPS system, a second civil signal at L2 (1227.45 MHz) and a third new civil signal at L5 (1176.45 MHz) will be added to future GPS satellites in addition to existing civil signal at Ll (1575.42 MHz) frequency. A wide band, compact, low profile, parasitically excited microstrip antenna design is presented to cover L2 and L5 frequencies. The proposed antenna design has a perfect square patch, which is parasitically excited by a nearly square patch fed at single point. Good impedance matching and circularly polarized radiation patterns have been obtained over wide frequency band by using bandwidth-enhancing techniques. The gain of the antenna is found to be more than 5.5 dB. |
