چکیده

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