The radiation of a point source above an infinite reflecting plane is analyzed. It allows us to set conditions on the reflection coefficient behavior in order to obtain a constructive interference between reflected and directly emitted waves. Then, a metallic photonic bandgap material (MPBG) is investigated to determine its spectral region bandgaps and reflection coefficient. As it could satisfy the conditions on the interference phenomenon on a wide band, the MPBG is used as an antenna reflector. At a frequency within the bandgap, the interference phenomenon is analyzed as a function of the distance between a dipole antenna and the MPBG. A two‐arm square spiral antenna is then used to examine the influence of the MPBG on the polarization of the radiated field. © 1997 John Wiley & Sons, Inc.
