Abstract:
In this paper, a circularly polarized antenna array comprising of four elliptical dielectric resonator is proposed for X-band applications. The array is excited by 1 × 4 substrate integrated waveguide based power divider. The proposed array offers an impedance bandwidth (for S11 <; -10 dB) of 17.3% (10.57-12.58 GHz) and 3dB axial ratio bandwidth of 7% (11.28-12.10 GHz). The antenna array is right hand circularly polarized (RHCP) and radiating maximum in broadside direction. The isolation between right hand circularly polarized (RHCP) and left hand circularly polarized (LHCP) fields is better than 12 dB. The proposed DR antenna array exhibits a peak RHCP gain of 11.42 dBic across the CP band.
