A Design of Ink-Printable Triband Slot Microstrip Patch Antenna for 5G Applications

In this paper, we present a slot microstrip patch antenna with ink-printing fabrication for 5G applications. The antenna has a three-layer structure with a slotted patch, operating at three frequency bands, namely, 5.73 GHz, 6.16 GHz and 8.34 GHz, with an average antenna gain of 5 dBi.
