摘      要：This paper presents the design and characterization of a via free planar single turn helix for 28 GHz broadband *** proposed antenna is designed using ROGERS RO4003 material,having a simple structure and end-fire radiation *** antenna comprises of a compact dimension of 1.36λ_(0)×0.9λ_(0) with a thickness of 0.0189λ_(0)(whereλ_(0) is the free-space wavelength at the central frequency of 28 GHz).Parametric study has been carried out to investigate the impact of key design parameters and to achieve an optimum *** show a good agreement between the simulated and measured results.A single turn helical inspired antenna covers−10 dB impedance bandwidth of 26.25-30.14 GHz having a peak gain of 5.83 dB and radiation efficiency up to 85%.Moreover,linear array configurations with 2 and 4 elements have been analyzed for applications with higher gain and space *** array configurations are suitable for applications having space constraints in one *** show that peak gain up to 8.2 dB and 11.1 dB can be achieved with 2 and 4 elements,*** to its simple planar and via free structure,this antenna is suitable for 5G communications and for sensing,imaging,IoT and tracking applications at 28 GHz band spectrum.
