摘要：

A compact array of circular polarised cross-shaped dielectric resonator antennas (XDRAs) is presented. The array consists of 2 x 2 XDRAs excited by microstrip-fed slot apertures in the X-band. By using sequential rotation to feed the XDRAs, the circular polarisation bandwidth is significantly increased from 5% for the individual XDRA to 16% in the array. The array also achieves a wide impedance bandwidth: a 10dB return loss was maintained over a 25% bandwidth.
