Abstract :
A new low cost patch antenna for high-precision applications in global navigation satellite systems (GNSS) is described. The antenna has been designed to operate for all existing satellite navigation frequencies in L-band including GPS, GLONASS and Galileo (1164-1300 MHz and 1559 - 1610 MHz). The right-hand circularly polarized radiating structure consists of a broadband matched square patch with a four- point feeding. The antenna exhibits a 10 dB beamwidth of more than 150deg, an antenna gain of more than 3 dBic and an excellent stable phase center. The desired radiation pattern roll-off and antenna gain are obtained using an electrically small radiating element with parasitic elements arranged around it. The dimensions of the developed antenna are a diameter of 150 mm and a height of 31 mm.
