A Conical Strip-Helical Antenna for Upper Mid-Band Spectrum of 5G

This paper present very compact design of conical strip-helical antenna for of 6GHz band application which is upper mid-band spectrum for 5G. The proposed design is having low loss and can be used for 5G enable devices. The conical strip-helical antenna is considered to function at 6 GHz frequency range to deliver dynamic support for 5G networks. The projected design shows circular polarization for entire range of bandwidth of 716 MHz. The substrate used within helical antenna is RT duroid 5880 with εr = 2.2. The novel-fangled intended strip structure is used on top of dielectric. It is then rolled into a conical helical shape to attain circularly polarized antenna. A bandwidth of 0.716 GHz with center operational frequency of 6.13 GHz is attained by the conical strip helical antenna. The designed antenna is showing decent gain of 13.2 dBi when operated at 6 GHz. The antenna is implemented and simulated using software tool Ansys HFSS. An achieved bandwidth is 11.68% with adequate return loss of − 10dB. The pro-posed antenna is working in axial mode having axial ratio less than 1.75 for the complete half power beam width. The proposed compact conical strip-helical antenna can be readily installed for moderate power, high gain, and wideband wire-less applications for upper mid-band range of 5G
