چکیده مقاله:
An outstanding square slot element, for x-band wireless applications with asymmetric coplanar waveguide fed (CPW) is proposed. Various shapes of metallic strips are utilized as grounded stubs for providing Right Hand Circular Polarization (RHCP) functionality and wide-band properties. By adjusting the proposed stubs and hook-shaped radiator, length and positions, wider impedance band width is obtained in x-band. In addition, asymmetric feeding technique is employed with semi-hook shaped radiating patch for efficient impedance matching and generating new resonances. By using rectangular slot and semi-hook shaped radiator good impedance matching is achieved in frequency band. Besides that, by introducing strips in ground plane, RHCP is achieved in x-band. The antenna size is only about 25×25×1 mm3, which covers the band from 6.5-12.9 GHz for S11
