Rectangular Loop mm-Wave Antenna for Wearable Applications

A compact rectangular loop antenna has been presented in this paper for wearable application. The antenna design consists of a rectangular loop and twin U-shaped patches composed of lossy copper whereas, roger is employed as a substrate with an epsilon value of 3. The overall size of the antenna covers 9x4mm which makes it suitable for wearable applications of 5G and B5G. The antenna is designed using a microwave studio as a simulation tool and evaluated by analyzing important results of reflection coefficient, impedance matching, and current distribution. The simulated results illustrate that the antenna radiates at 60 GHz frequency with a -10dB impedance bandwidth of 1.2 GHz. The proposed antenna offers a gain of 7.5 dBi with a 3 dB angular width of 33.2 db. The antenna is excited using a coaxial feeding technique which is in good matching. The designed antenna offers good impedance and radiation features with a compact size which makes it an appropriate candidate for mmwave wearable application for 5G and B5G.
