ملخص المقالة :
circularly-polarized antenna is built based on new SIW(substrate integrated waveguide)structure which contains cavity-backed resonator and a conventional polarized ring with twosquare slits in inner and outer ring that differ 90° at position and is proposed for right-handedcircular polarization (RHCP) and fabricated in two separate layers. A broadband impedancebandwidth of 13.9% and a RHCP axial ratio of 0.5GHz have been obtained under thecondition of less than VSWR ≤2 and axial ratio≤ 3 dB, respectively.
