Miniatured annular ring loaded patch antennas
2007 IEEE Antennas and Propagation Society International Symposium, 2007 The proliferation of wireless communication systems has promoted the development of miniaturized antenna designs. Annular ring patch antennas are reported to reduce antenna size. In this paper, several novel compact probe-fed annular-ring microstrip patch antennas are presented. In order to reduce the antenna size and provide a suitable input impedance
