ENHANCING 5G CONNECTIVITY WITH MULTI-SLOTTED PATCH ANTENNAS: SUB-6GHZ AND SUB-7GHZ WIRELESS APPLICATIONS

This paper presents a low-profile multi-slotted patch antenna for fifth-generation (5G), Sub-6 GHz/Sub-7 GHZ and- long term evolution (LTE) communication applications. The studied antenna comprised of a stepped patch and a ground plane. The antenna is fabricated on an FR4 substrate with a relative permittivity of 4.3 and a thickness of 1.5mm. The simulated and measured results are in good agreement, which validates the design. The antenna has a size of 20*30*1.5 mm3 and is fed by a Microstrip line. To attain the required operating band, three slots have been inserted within the patch. The insertion of the slots enhances the capacitive effect and helps the prototype antenna to achieve an operating band ranging from 3.19 to 9.4 GHz (S11 less than 10 dB). The wide band antenna presented in this paper offers omnidirectional stable radiation patterns, good gains, and efficiency with a compact size which make this design an ideal contender for wireless fidelity (WiFi), wireless local area network (WLAN), LTE, and sub-6 GHz 5G communication applications.
