Abstract
An FSS based circular polarizer for high-speed wireless communication at 75 GHz is presented. It has been designed on a low loss substrate with cross-dipole elements. Both simulation and measured results showed more than 98% circular polarization at 75 GHz. Moreover, 3 dB axial-ratio bandwidth of 6.8 GHz (Simulation) and 7.8 GHz (Measured) has been achieved. The proposed design has many advantages over the recently published research such as simplicity, low-profile, percentage bandwidth, frequency of operation and relative insertion loss.

Summary
The communication in circular polarization mode is very important in tracking and radar communication applications. It has many advantages and disadvantages to linear polarization. One way of achieving circular polarized wave communication is the use of electronically steerable antenna arrays [1] [2]. Design and development of such systems in which electronic circuitry needs to be integrated with arrays of antennas is a challenge [3] [4]. Most of such antenna systems provide linear polarization [5] [6]. A solution to this problem is to design and develop a linear polarized an-
