A stepwise and effective procedure for impedance matching of slot-fed planar antennas. application to the design of wide band printed antennas and reconfigurable EBG resonator antennas

In this paper, the authors propose an effective design methodology for the impedance matching of aperture-coupled microstrip antennas. Our impedance matching method is described in detail in section 1. Then it is applied to design a 20%-bandwidth stacked patch antenna at 7GHz in section 2, as well as a Ku-band reconfigurable EBG resonator antenna with an embedded slot-fed patch antenna and a reconfigurable partially reflecting surface in section 3.
