In this article, a semi-circle shaped planar monopole antenna is proposed for 5G applications for improved gain. The gain of the proposed antenna is increased by loading the ground plane with a proposed FSS layer. The hexagonal shaped unit cell is proposed to construct the FSS layer. This article presents the composition of architectural equations for creating the band pass hexagonal reflector employing hexagonal geometry and planar monopole radiator. The proposed antenna dimension was in compact size of 20 18 mm2. The monopole and FSS substrates both fabricated on FR4-substrate (r 4.4) with a height of 1.6 mm. The hexagonal patches are placed with the spacing of 0.6 mm and 14 mm below the main radiator The hexagonal reflector and printed monopole antenna shapes are designed for n77 and n78 NR bands. The ANSYS HFSS software is used to execute the simulations. The prototype is fabricated and the results are validated by measuring the S parameter, Gain and Radiation pattern. The results are validated by taking measurements in Anechoic chamber with the aid of VNA with 0.6 mm spacing between the elements. The measured/simulated fractional bandwidth of the antenna is 19.14 %, with a peak gain of 6 dBi and a maximum directivity of 6.2 dBi. The proposed hexagonal FSS structure provides better gain (nearly 6 dB improvement) and impedance matching from3.9 GHz to 5.04 GHz and well suited for 5G applications. |
