A planar antenna is described that is made up of a line source embedded in a structure containing a metal reflector and a dielectric layer coated with metal strips. We have fabricated and measured the radiation characteristics, including the return loss and radiation pattern. In addition to the experimental studies, the rigorous mode-matching method(More)
An elliptical polarization antenna with unsymmetrical angular axial ratio distribution is proposed in this work. The RF current distribution on radiation patch is redistributed to increase the angular axial ratio variation. This property can suppress the received signal strength from unwanted direction. It's suit for point to point communication and radar(More)
