Design of a miniaturized microstrip patch antenna for triple-band operation in X, Ku and K band with band-notch characteristics

摘要

The paper proposes a novel compact microstrip patch antenna with high radiation efficiency and directivity alongwith an effective wide bandwidth of operation. The antenna designs are simulated and their performance are analyzed for different parameters like Return loss (S11), Voltage Standing Wave Ratio (VSWR), Current Distribution, and Farfield Radiation Plot on CST (Computer Simulation Technology Microwave Studio) software for a tri-frequency band operation in the X band (8-12 GHz), the Ku band (12-18 GHz) and the K-band (18-27 GHz) as per the specified IEEE standards.
