A Compact Ultra-Wideband Microstrip patch Antenna for 5G and WLAN

A compact ultra-wideband microstrip patch antenna for 5G communication and WLAN is presented in this study. The proposed antenna, consisting of the radiating patch with double cross-shaped slots, circular defects ground structure (DGS) and a rectangular parasitic patch, is printed on the F4B substrate. To achieve the characteristics of broadband and compaction, the double cross-shaped slots and circular DGS are respectively embedded in the radiating patch and ground plane. Moreover, the implication of the parasitic patch realizes the impedance match. The results show that the proposed microstrip patch antenna has the characteristics of broadband and compaction. More precisely, the proposed antenna can operate in the frequency range of 3.28-6.38 GHz, e.g. the relative bandwidth is 64.2%.
