Abstract

There is disclosed an array of m dielectric antennas and a feed mechanism for transferring energy between each dielectric antenna and a single feed point, wherein each dielectric antenna is tuned to an impedance of substantially n ohms, and wherein the feed mechanism connects the dielectric antennas to the single feed point in such a way that the single feed point is matched to an impedance of substantially n/m ohms. By tuning each dielectric antenna to a higher impedance than that of the single feed point, a feed point impedance matched to a predetermined impedance may be provided without requiring lossy and narrow bandwidth components such as quarter-wavelength transmission lines and the like.
