Abstract
Ability of novel annular waveguide slot antenna (AWSA) arrays to radiate any of the four main polarizations (circular left hand or right hand (CLHP or CRHP) or linear horizontal or vertical) is presented in this paper for the first time. By forming a 4-element AWSA array and proposing simple feed coefficients, the desired polarization will be achieved from the resulted array. Such polarization agility would have a wide range of applications in modern wireless communication systems.
