- Abstract
An integrated antennas are presented with dual frequencies and dual circularly-polarized (CP) in a common aperture. The proposed integrated antennas are consisted of dual crossed dipole antennas (CDA) with stacked structure, which used 90° self-phase shifting structures in both CDAs for CP wave achieving by adjusting the proportion of the orthogonal arm lengths for 90° phase difference forming. The upper CDA covers 4.7% relative bandwidth from 1.55GHz to 1.625GHz with VSWR less than 2 and axial ratio (AR) less than 3 dB of left-hand CP (LHCP) and the nether CDA covers 3.4% relative bandwidth of 2.44~2.525GHz for right-hand CP (RHCP).
