Microstrip Patch (MP) antenna is a small, lightweight antenna that finds most applications in present-day wireless communication devices because of its easy fabrication and ability to work in high-frequency applications. That makes such types of antennas critical especially in indoor wireless communication in the license-free spectrum for the effective accomplishment of improved connectivity and cost reduction without expensive licensing. Frequency Selective Surfaces (FSS) are structures purposely designed to allow the filtering of electromagnetic waves in a controlled way based on frequency, allowing for transmission of the wanted frequencies and inhibiting others. Merging with the MP antenna, FSS adds a great performance, particularly in the context of enhanced bandwidth, gain, and interference reduction. All of this leads to better and higher-efficiency wireless communication fit for indoor environments where uninterrupted and highly reliable connectivity matters. This paper presents a design and analysis of a compact MP antenna for indoor applications at 62 GHz in the license-free spectrum using CST software. The proposed design comprises a conventional Roger’s RT5880 substrate-based MP antenna; on top of which there is an FSS superstrate, similar to an umbrella, kept at a separation of 2.2 mm. The proposed design is encouragingly showing a good bandwidth of 1.26 GHz with a return loss of −37.97 dB and a gain of 9.7 dBi which indicates to the best impedance matching as well as performance; hence, it is suitable for indoor applications.
