Abstract :
A broadband impedance matching circuit for a slot coupled microstrip patch antenna is proposed, analyzed and experimentally examined. In order to enhance the bandwidth of an existing antenna, an appropriate impedance matching network using filter-design techniques is designed and implemented. Numerical results for the antenna impedance bandwidth are compared with measurements, and far-field patterns are calculated. Agreement between the experimental results and numerical predictions has been obtained.
