Over the past one decade, there is a rapid growth in the development of wireless communication applications. The performance of all such systems completely depends on the design of the antenna. Microstrip antennas are preferred for most of their applications. A low profile microstrip antenna with stable radiation pattern in a relatively wide band is presented for 5G operation. This paper presents a dual band rectangular microstrip patch antenna. This antenna is designed over an operating frequency of 3.48GHz (5G band) and 6.12GHz using the substrate material FR-4 which has a dielectric constant of 4.3. The design antenna can be used for 5G applications such as enhanced Mobile Broadband (eMBB), Massive 00machine type communication (IoT), Ultra reliable low latency communication. The designed antenna has low profile, low cost, easy fabrication and good isolation. The proposed antenna is designed for the purpose of aeronautical radio navigation and mobile satellite communication. The return loss of the proposed antenna is -26.26dB with a good total efficiency of -3.85dB. A prototype of the antenna was fabricated and achieved a good directivity gain of 3.21dBi with a VSWR of 1.1 at the resonant frequency. Experimental validation of technique is carried out and measured results were found to be comparable -with simulated results.
