Low Profile Multi-slotted Patch Antenna for Lower 5G Application

A low profile multi-slotted patch antenna is developed for fifth generation (5G) wireless communication application. The required wide operating band is achieved by good coupling between the multi-slotted radiator and the ground. The partial ground not only helps to reduce antenna size but also the ground plane dependency and undesired cross-polarization field. The antenna is enabled to operate at 3.15 to 5.61 GHz band for S
₁₁
≤ -10 dB. The wideband antenna presented in this paper also achieved good gain and efficiency, and exhibits nearly omni-directional radiation patterns which make it very suitable for being used in portable communication applications.
