A miniaturised Ka/V dual band millimeter wave antenna for 5G body centric network applications

Abstract

Body centric Networks (BCNs) are the most important and attractive part of the next generation (5G and beyond) wireless technologies having a plethora of applications in day to day life. However the design of antennas for BCNs is a challenging task. Such antennas should have small size, light weight, higher gain and larger bandwidth besides having a stable radiation pattern under the influence of human body effects. This paper presents a miniaturised Ka/V dual band mmWave microstrip antenna for 5G BCN applications. The antenna has very small dimensions of 2.28 × 3.06 × 0.14 mm3 and operates at 33.5 GHz (Ka band) and 60.8 GHz (V band). The performance of the antenna is examined for “Off-body, On-body and In-body” BCN application scenarios. The radiation pattern, return loss, peak gain and −10 dB bandwidth results reveal that the antenna performs quite well at all interested frequencies. A comparative study with state of art mmWave antennas also shows the effectiveness of the proposed antenna.
