Wearable Finger Ring Antenna Array for 5G/mmWave Applications

Body-centric wireless communication has become an important part of the fifth-generation communication systems. Many modern applications such as, telemedicine, health monitoring and personal entertainment are adding to its popularity. In this work, a wearable finger ring antenna array radiating at 28GHz has been proposed for the 5G/mmWave communication system. The antenna is composed of a microstrip patch array, which is mounted to a Teflon ring base, to make it wearable. CST Microwave Studio has been used to model, simulate and optimize the antenna. The simulated results illustrate that the proposed design provides a good return loss at the desired frequency with a peak gain of 5.14dB. Good performance in terms of bandwidth and radiation characteristics, along with a miniaturized form factor makes it a suitable candidate as a wearable antenna to communicate at the mmWave frequency spectrum.
