In this study, technques of cross-polarization suppression for the coplanar waveguide (CPW)-fed monopole antenna with an asymmetric ground plane have been presented. By appropriately etching a notch and embedding a four-slot array in the ground plane, the horizontal current component of the ground plane can be efficiently decreased, thus suppressing the cross-polarized radiation at the broadside direction...
Frequency selective reflector (FSR) is useful to actualize multi-band reflector backed dipole antennas. This paper investigates a suitable FSR element shape for the FSR backed dipole antenna forming sector radiation pattern, which is suitable for mobile base station antennas. Three element shapes, Gang Buster, Jerusalem Cross, and Square Loop are considered. Radiation patterns are calculated by the...
