摘要: Abstract A small size coplanar waveguide-fed dual wideband circularly polarized square slot antenna (CPSSA) is presented. It composed of an inverted C-shaped patch, grounded-L strip, a pair grounded spiral slots and horizontal rectangular slot. The circular polarization (CP) achieved by embedding strip slots. By engraving in left corner CPW ground plane, the 3-dB axial ratio bandwidth (ARBW) lower band enhanced it also generates another CP at about 12 GHz notched band. From experimental results, observed that ARBWs proposed are 74.62% (5.01 GHz, 4.21–9.22 GHz) 12% (1.37 GHz, 11.26–12.62 GHz) while impedance bandwidths 92.70% (6.48 GHz, 3.75–10.23 GHz) 13.70% (1.63 GHz, 11.12–12.75 GHz) upper bands, respectively. has peak gain 3.67 6.36 dBic respectively, with good LHCP radiations. overall 20 × 20 × 1 mm3.
