Abstract
In this paper, various structures of patch antennas are designed with FR4 substrate material. All the proposed antennas are designed without distorting the ground. For simulations, industrially accessible High Frequency Structural Simulator (HFSS) is used in this investigation. The characteristics like VSWR, Return loss, Axial ratio are studied and based on the results the best structure is selected which resonates at two frequencies one in the X-band (8GHz-12GHz) and the other in the Ku-band (12GHz-18Ghz). The s11 value crosses the -20 dB line at both resonant frequencies (8.96GHz and 13.36GHz) and the VSWR has an average value of 1.5 at both resonant frequencies. The proposed patch antenna structures are excited with lumped port and discussed below.
