Broadband Polarization Rotating Frequency Selective Surface With Polarization Selection

IEEE Antennas and Wireless Propagation Letters
In this letter, a broadband polarization rotating frequency selective surface (BPR-FSS) is reported based on antenna–filter–antenna module. In the operating frequency range of 5.76 GHz to 7.12 GHz, the structure can convert y-polarized incidence to x ...

Frequency selective surfaces for radio astronomy–characteristics of 40/80‐ghz fss

Electronics and Communications in Japan (Part I: Communications), 1990
AbstractFrequency selective surfaces (FSS) have been developed for applications to the 45‐m telescope of the Nobeyama Radio Observatory (NRO), the National Astronomical Observatory (NAO), Japan, for simultaneous observations of radio astronomical sources at the 40‐ and 80‐GHz bands.The Jerusalem‐cross array configuration has been used for the ...

Analysis of interaction between microwave antennas and frequency selective surface (FSS) radomes

IEEE Antennas and Propagation Society International Symposium. Digest. Held in conjunction with: USNC/CNC/URSI North American Radio Sci. Meeting (Cat. No.03CH37450), 2004
The interaction between the microwave antenna and the FSS is analyzed by using a modified plane wave spectrum approach. The analysis of the antenna is carried out by using CFDTD technique in order to obtain its aperture fields which are in turn used as an excitation for the FSS.
