Design and Implementation of Quadrifilar Helical Antenna for 60 GHz Band Application

In this paper an extremely compact 4-wired Quadrifilar Helix Antenna (QHA) designed and simulated. The proposed Quadrifilar Helix antenna is exhibiting narrow-band radiation pattern around 60GHz frequency spectrum. The antenna has gain of 9-dBi at center operating frequency. The frequency of operation is 60 GHz. The simulated narrow band impedance bandwidth of the design is 2.1% with acceptable return loss (-10dB). Antenna is functioning in axial mode having axial ratio less than 1.1 for complete band of design operation. The consequences of design variation on the input reflection coefficient, radiation pattern with directivity and maximum gain of the QHA are investigated and the outcomes are examined for working frequency of the 60 GHz. The compete design simulation is executed through design and simulation tool Ansys high-frequency structure simulator (HFSS). The proposed antenna must be designed carefully because of its small dimensions. But it can be easily installed in any hand-held low power 5G enable devices. The offered antenna is aimed to work at millimeter wave region for added capability in the 60-GHz band (conventionally known for the WiGig) and also to stablish active system support for current and upcoming 5G networks.
