Abstract

A new design of dual band compact microstrip antenna is proposed for Ku-band applications. Dual band is achieved using three pairs of thin slits from the sides of a rectangular patch and feeding with a microstrip feed line. The result shows that a return loss of -32. 9dB is achieved at the first resonant frequency of 12. 72GHz, and -14. 4dB is obtained at the second resonant frequency of 14. 4GHz frequency with VSWR ? 2indicating improved matching conditions. The results ofsimulation are return loss, radiation pattern, VSWR, and band widtharepresented. The design is performed by using Ready-madeSoftware package Zeland- IE3D. The antenna is fabricated using thin film and photolithographic technique and measured using the Vector Network Analyzer. The final result shows that good agreement between the simulated and measured results.
