Three configurations of compact planar multistub antennas are proposed in the frequency range of 27–29.5 GHz as candidates for the 5G standard frequency band. Each antenna consists of the same feeding part configuration but different structures for the dipole, director, and reflector parts. The feeding part is based on the substrate integrated waveguide (SIW) technology which results in compact size. The TE10 dominant mode is considered in the design procedure by HFSS software simulations. The proposed antennas have been simulated, fabricated, and measured (for S11, E, and H pattern). The simulation and measurement results show reasonable agreement for S11 and radiation patterns of E- and H-planes and impedance bandwidths. Moreover, for specific absorption rate (SAR) estimation, a three-layer human head model (skin, skull, and brain) is placed next to the antennas as the exposure source. The simulation results show the performance of the proposed antennas for low-SAR, which make them good candidates for safe usage concerning the negative impact of millimeter waves (mmWs) on human health. Finally, a comparison table is presented which verifies the compact size of our proposed antennas.

“…In [35], the effect of the dielectric and electrical properties in a human body that vary between frequencies. Due to these specific properties and the waves that are observed by the body makes the gain of the antenna to be increased when used in the front end of the body [36]. There exists many type of UWBs that uses a variety of slot features.…”

A planar UWB antenna is intended to deploy for on-body applications. The antenna is typically to manage for free space and placed on a harmonized phantom. The calculations are performed for return loss, radiation pattern and gain. The performance of the UWB antenna ranges from 3-11.2GHz. The main feature of the antenna depicts superior impedance level with good satisfaction on on-body propagation. Here, the observation between the phantom and antenna are carried out which results in input matching of the proposed antenna. The return losses are very slightly affected but the Gain of the antenna is seen decreasing significantly, after placing the antenna on the phantom.
