A Wideband Small-Footprint Platform-Insensitive Monopolar Patch Based on Slot-Assisted High-Order Mode Tailoring
A wideband, compact monopolar patch antenna with an inherent filtering response is presented in this paper. By employing a slot-assisted mode-tailoring technique, the field distributions of several higher-order modes at the patch center are engineered to produce a stable monopolar radiation pattern with enhanced bandwidth. The closed-form analysis indicates that increasing the current intensity at
