Design of a Compact Dual Band Microstrip Antenna for Ku-Band Applications
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 less than or equal to 2 indicating improved matching conditions. The results of simulation are return loss, radiation pattern, VSWR and band width are presented.
