Abstract

Transmit-array (TA) has advantages such as low profile, easy fabrication, flexible element structure, and multi-function etc. It receives spherical wave and adjust its phases to re-radiate forwards. TA avoids the effect of feed blockage existing in a reflect-array, can realize arbitrarily linear polarization transform well. In this paper two kinds of broadband element of TA with polarization transform are proposed, their properties of phase compensation, polarization transform and transmission efficiency are analyzed and compared
