A microstrip phased antenna array constituted by the association of two kinds of monolayer rectangular patches is presented. The frequency bandwith of such an antenna is larger than the bandwith of usual monolayer microstrip arrays. This antenna is made of two imbricated triangular grid arrays. The first array is fed, and the second is...

A stacked dielectric resonator antenna (DRA), composed of an annular ring excited by a coaxial probe and two cylindrical dielectric resonators (CDRs), is studied experimentally for three‐frequency band operation. A maximum frequency ratio of 1.75 is achieved between higher and lower frequencies, and quite similar radiation patterns are obtained...

A miniaturised C-patch antenna excited by means of a coaxial probe is described. The antenna consists of two stacked C-shaped elements connected together with a vertical conducting plane. The antenna is designed on an air substrate and offers attractive dimensions, being five times lower than those of a conventional half wavelength microstrip...
