X-band coaxial monopole antenna with an additional metal screen

Abstract

The novel coaxial monopole antenna design with an additional metal screen is presented. The radiation characteristics of this antenna are investigated depending on a distance between the ground plane and additional metal screens, as well as on a size of the latter. Measured and calculated radiation patterns are compared within limits of the operative frequency band and their revealed distinctions are discussed. The antennas characteristics allow pronounce that it can be considered as a promising candidate for various practical applications both a single radiator and a composite element of antenna arrays.
