Abstract
In this paper, a modified Swastika slot on a Circular Patch antenna has been studied and proposed that operates in X, Ku, K, and Ka band. The proposed antenna is a novel design technique where the design of the modified swastika shaped slot is done in different iterations. High Frequency Structural Simulator (HFSS) version 13.0 which is based on finite element method is used for the simulation purpose. The proposed antenna is simulated and found to operate at five different resonant frequencies at 10.4 GHz, 16.5 GHz, 21.8 GHz, 26.9 GHz, and 29.9 GHz. The designed antenna shows better return loss, low VSWR, high antenna gain with good bandwidth and better radiation pattern characteristics where it can be used in satellite and RADAR applications.
