Multi_Slotted Antenna for 5G Application for Wireless Communication

A low-profile multi-slotted antenna for LTE and sub-6 GHz 5G applications is designed, fabricated, and measured. The footprint of the proposed antenna is made up of a steeped rectangular radiating element with three slots and a partial ground plane and is printed on both sides of an FR4 microwave substrate.

It is evident from the results that the multi-slotted patch coupled well with the ground plane and the presented antenna is able to achieve a wide operating band of 3.15–5.55 GHz (55.2%) to cover all the sub-6 GHz 5G bands, WiFi, WLAN, and LTE bands of 22/42/ 43/46. Moreover, it achieved good gain and efficiency and exhibits stable omnidirectional radiation patterns which make it a suitable candidate to be used in the newly introduced 5G applications in addition to the existing WiMAX, WLAN, and 4G applications
