Abstract

In this work, a broadband transmissive type linear-circular polarizer with wide angular stability is demonstrated. It shows a 3 dB Axial Ratio (AR) bandwidth of 21.05 GHz (from 20.17 - 41.22 GHz) with 68.58 &#x0025; fractional bandwidth (FBW) covering K and Ka-bands. The angular stability of the converter is examined, and it possesses a stable AR response up to 50&#x00B0; (for &#x03D5; &#x003D; 0&#x00B0;) and 40&#x00B0; (for &#x03D5; &#x003D; 90&#x00B0;). The design is compact with the periodicity of 0.107&#x03BB;<inf>L</inf> x 0.141&#x03BB;<inf>L</inf>, where &#x03BB;<inf>L</inf> is the free-space wavelength corresponding to the lowest frequency over the broadband. Authors&#x0027; strongly believed that the proposed design has broadband 3 dB AR, better angular stability, and compactness made it suitable for countervailing the effect of Faraday rotation in satellite communication applications.
