• A crossed dipole that is loaded with a magneto-electric dipole to produce the wideband and wide-beam circularly polarized radiation characteristics is proposed. The crossed dipole is incorporated with double-printed vacant-quarter rings to feed the antenna. The antenna is backed by a metallic cavity to provide a unidirectional radiation pattern with a wide axial-ratio (AR) beamwidth and a high front-to-back ratio. Experimental results showed that the prototype with an overall size of 120×120×30.5 mm 3 has a |S 11 |<;-10 dB bandwidth of 1.274-2.360 GHz and a 3-dB AR bandwidth of 1.39-1.82 GHz. The antenna showed a right-hand circular polarization (CP) radiation with a very wide 3-dB AR beamwidth (>165°) and a high radiation efficiency (>94%) within the operational bandwidth.
