An ACS-fed Multi-band Antenna for 5G and WLAN Applications

In this paper, a multi-band antenna with an asymmetric coplanar strip (ACS) fed is proposed for 5G and WLAN applications. The proposed antenna consists of ACS feeding structure, stubs, and a capacitance loading to implement the multi-resonance to meet the requirement of the two different modes. The proposed antenna is created in the HFSS and the designed results have been discussed in detail by considering the varying antenna parameters. The results show that the proposed dual-band antenna can operate at 3.5 GHz and 5.08 GHz with a −10-dB fractional bandwidth of 9.6% and 29.6%, respectively. Moreover, the proposed dual-band antenna has omnidirectional radiation patterns at both operating bands.
