antenna radiates above a closely spaced artificial magnetic conducting (AMC) reflector. The electromagnetic
band gap (EBG) performance was evaluated with an equivalent waveguide feed in place of one half-wavelength
section of the slot antenna. Experimental results for the final antenna design (with a size of 1.02 0 × 0.82 0 ×
0.063 0), mounted on 1.5 0 × 1.5 0 back plate, exhibit a 5% impedance bandwidth, maximum gain in excess of
10 dBi, low cross-polarization, and a front-to-back ratio of approximately 25 dB.
