A Slot-Loaded Wideband Patch Antenna Fed With a Dual-Function U-Resonator for Stable Radiation

In this paper, a slot-loaded patch antenna fed with a dual-function U-resonator is proposed to realized bandwidth enhancement and even-modes suppression. Initially, a transverse slot is loaded to the radiating patch so as to reshape current distribution of high-order mode and suppressed its sidelobe radiation. Then, a U-resonator is introduced to improve the radiation performances of the resultant...
