Compact Dual-Band Antenna with High Gain and Simple Geometry for 5G Cellular Communication Operating at 28 GHz and 44 GHz

This work elaborates a dual-band antenna which finds its applications in mobile and satellite communication systems within the context of 5
^th
generation (5G) technologies. The proposed antenna is designed by using semi-flexible substrate material Roger/RT duroid 5880 with an overall dimension of
$15\ \text{mm} \times 15\ \text{mm} \times 0.79\ \text{mm}$
. The antenna structure is composed of dual circular patches along with elliptical patch, which is further loaded with two elliptical slots. The proposed antenna has the capability to operate from 25.8 – 29.9 GHz and 41.8 – 52GHz with central frequencies at 28 GHz and 44 GHz used for mobile and satellite communications, respectively. The proposed propagation device includes various advantages including its compact size with low geometric complexity, high gain and wide operational bandwidths which makes it good potential candidate for mm-wave applications and 5G communication systems.
