ASide-Edge Microstrip Antenna for 5G Applications.

In this paper, an innovative miniaturized microstrip antenna installed on the side edge of a mobile smartphone is constructed and explored. The side-edge antenna operates at 3.71 GHz with a 10-dB covered bandwidth of 150 MHz, and it is intended for the applications located within the sub-6 GHz band of the fifth-generation wireless communication. In the operational frequency range, the planned antenna can attain a peak realized gain of 3.38 dB and 57.69 % radiation efficiency. The antenna reveals a directional radiation pattern oriented to the outer side of the mobile terminal.
