Electromagnetically Coupled Microstrip Dipole Antenna Elements

Abstract

An electromagnetically Coupled (EMC) member of the microstrip dipole antenna family is described. Several configurations differing in the dipole location and in the amounts of electric and magnetic coupling to the micro-strip line yield different bandwidths, efficiencies and construction simplicity. The transformer action inherent in EM coupling allows a wide variation in matching conditions. Radiation characteristics of the element and examples of arrays constructed with the element are described.
