Design of a Compact Wideband Bow-Tie Dielectric Stacked Patch Antenna for Ku-Band Spectrum

The present communication gives the design of a compact patch antenna module to be functional from 12 to 18 GHz EM spectrum which is given the name Ku-band. The design of the antenna focuses the dielectric stacking approach. Base substrate is chosen FR4 dielectric and it consists of microstrip feed line and a partial ground plane on its top and bottom respectively, a dielectric material along with patch having bow-tie shape is stacked on the base substrate. The proposed antenna is designed and simulated using ANSYS HFSS. The FEM based simulations proven the -10 dB return loss criteria and the VSWR below 2.0 are satisfied for the proposed model under 12.07-19.11 GHz band. The geometrical aspects of this model ensures the wideband functionality of the antenna with a peak gain of 6.23 dB.
