Abstract: In this antenna study, a compact thin profile wide band patch antenna is introduced for fifth generation. The overall dimensions of this compact antenna is 5 mm x 5.26 mm only, operating in the 28 GHz frequency in Ka-band. Built on the Rogers Rt/Duroid 5880 substrate having thickness of 0.254 mm, the antenna provides 2.1 GHz (27.3-29.2 GHz) of bandwidth at below -10dB reflection coefficient. The novel proposed design is fed by the coaxial feed having inner radii of 0.254 mm. The motive of this study is to improve the bandwidth by utilizing the DGS (Defective Ground Structure) technique and further to procure the high impedance matching, slotting technique is applied on the partial ground plane in which an X shaped slot is engraved resulting a reflection coefficient of -20.03 dB. The proposed antenna provides desirable values of Gain and Directivity of about 5.2 dB and 6.16 dBi respectively. Discrete parameters of designed antenna such as voltage standing wave ratio, radiation patterns, surface current distribution are also evaluated to study antenna characteristics which implies for 5G applications.
