In this paper, a very small broadband circularly polarized planar antenna fed by coplanar waveguide is designed and fabricated. The antenna is composed of a beveled rectangular radiator patch, a square patch, two inverted L-shaped grounded strip lines, and two semicircles etched on ground. Additionally, to realize the circular polarization a new structure(More)
A dual band circularly polarized (CP) antenna for WiMAX and WLAN application is proposed. By placing a fork-type parasitic element with a ground plane and a rectangular stub connected to the ground, desirable CP dual band characteristics are achieved. The measured results exhibit %22.2 (3/2–4 GHz) and %21/4 (5–6/2 GHz) impedance bandwidth with(More)
