Abstract

This work evaluates the performance of two ILA with different dielectric materials. Two elliptical ILAs of 32 mm radius are designed using Rexolite (є r = 2.53 and tanδ = 0.0013) and PREPERM® L450 (є r = 5.01 and tan.i = 0.0046) materials. The gain and beam-steering properties of these ILAs were thoroughly investigated using raytracing simulations and measurements at E-band. Despite the higher loss tangent, the ILA with L450 material gives 29.3 dBi gain compared to 28.7 dBi of Rexolite material at 73 GHz. The measured gain scan loss for steering angle of the 24º beam is 4.3 dB and 4.9 dB for the Preperm-ILA and Rexolite-ILA, respectively. Additionally, the work focuses on the dielectric property characterization of the L450 material at millimeter wave frequencies.
