Abstract :
A new type of unit cell featuring wideband low loss characteristics is proposed for transmit-arrays (TA) and frequency selective surfaces (FSS) in Quasi-Optical applications. The TA is realized as a non-uniform array of antenna-resonator-antenna (ARA) elements and the FSS is realized as a uniform array of ARA elements. Each ARA element is a three layer structure consisting of two patch antennas and a slot resonator. The ARA elementary cell is designed and verified using finite element method simulation. A free space Gaussian optics measurement system (GOMS) is utilized to characterize the elementary cell. The measurement results show a 20.7% -3dB (12.2% -10dB) bandwidth and a maximum in-band insertion loss of <;0.2 dB for 42 GHz.
