Parasitic Elements Shorted to Ground to Enhance the Bandwidth of a Dual-Polarized Antenna
International Journal of Antennas and Propagation, 2022 An ultra-wideband dual-polarized antenna covering multiple communication standards such as LTE700/GSM850/GSM900 is proposed in this paper. The antenna consists of two dipoles that are perpendicularly placed to each other. The two dipoles can generate +45°
