N2 - A dual-band, wide-beam, circularly-polarised crossed asymmetric dipole antenna is presented for global positioning system (GPS) applications. Each dipole arm has an asymmetrically barbed arrowhead and contains two different-sized printed-inductors to reduce the length of the primary radiating element and to achieve dual-band operation. At 1.575 GHz, the antenna has a gain of 7.5 dBic, a radiation efficiency of 97.4%, and a 3dB axial ratio (AR) beamwidth of 143° and 152° in the x-z and y-z planes, respectively. At 1.227 GHz, the antenna has a gain of 6.3 dBic, a radiation efficiency of 90%, and a 3dB AR beamwidth of 132° and 140° in the x-z and y-z planes, respectively.
