A MULTI-INSET MICROSTRIP PATCH ANTENNA FOR 5G WIRELESS COMMUNICATIONS

This paper presents a low-profile multi-inset patch antenna for long-term evolution (LTE) and fifth-generation (5G) communication applications. 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 insertion of the inset enhances the capacitive effect and helps the prototype antenna achieve an operating bandwidth ranging from 2.373368 to 2.430401 GHz. The performance of the antenna has been analyzed in terms of resonant frequency, return loss (S11), gain (dB), directivity (dBi), and percentage bandwidth. The proposed antenna has a measured directivity of 7.186 dBi at a resonating frequency of 14.23 GHz. The wide band antenna presented in this paper offers Omni-directional stable radiation patterns, good gains, and efficiency with a compact size which makes this design an ideal contender for wireless fidelity (WiFi), wireless local area network (WLAN), LTE, and sub-6 GHz 5G communication applications.
