In this paper, with the application of dielectric resonator antennas(DRA), a novel design of a shared-aperture dual-band dual-polarized (DBDP) array working in the Ka/Ku bands is proposed. At Ka-band, aperture-coupled microstrip patches are selected as the radiating elements. At Ku-band, Crossed dielectric resonator antennas(DRA) are selected as the radiating elements. The array which comprises 2×2...
A novel dual-polarized dielectric resonator antenna with two groups of differential feeding networks is presented. By using this feeding way, the port isolation[6] of 28 dB and the cross-polarization level of 35 dB are got. Since its feeding network is symmetric, a symmetric radiation pattern is achieved. The simulated −10-dB impedance bandwidth is 13% (2.3–2.6GHz) for the WLAN application.
