Design of an LCP-based antenna array for 5G/B5G wearable applications

Abstract

Interest in wearable applications providing early medical diagnostics and reliable communication to the remote observation station is ever increasing. A flexible microstrip patch antenna array designed on a liquid crystal polymer (LCP) substrate is presented in this paper. The designed antenna array consists of five radiating patches fed by a combination of series transmission lines. The simulated results show that the antenna resonates at 52 GHz with-10 dB impedance bandwidth of 1.34 GHz. It offers a gain of 3.5 dBi and 3-dB angular width of 72.3°at the operating frequency along with low weight, low cost and ease of fabrication. Good impedance and radiation characteristics with small size and low profile make this antenna ideally suited for low latency wearable applications in 5G/Beyond 5G networks.
