Low-Cost Sub-THz Linear to Circular Polarizer
摘要
We introduce an approach to produce inexpensive linear to circular polarizers for the sub-THz spectral regime with either left or right handedness. Our design consists of a cross-dipole array of slot antennas, fabricated on paper using a fast and inexpensive process. We demonstrate a prototype designed for a frequency of 200 GHz, showing a low axial ratio and acceptable insertion loss.
