Low cost 60 GHz new thin pyralux membrane antennas FED by substrate integrated waveguide

Tristan Sarrazin, Hamsakutty Vettikalladi, Olivier Lafond, Mohamed Himdi, Nathalie Rolland

A low cost technology based on FR4 and thin flexible Pyralux substrate to develop membrane antennas/array with high efficiency and wide bandwidth for high speed V-band communication systems is proposed in this paper. A new low cost thin Pyralux substrate with a thickness of 75 μm, relative…

Coupling effect of split ring resonator and its mirror image

F. Zhang, Q. Zhao, J. Sun, J. Zhou, D. Lippens

We report on experimental and numerical studies on the coupling effect of a single split ring resonator (SRR) and its mirror image inside an X-band hollow waveguide. It is shown that, for single SRR with gap bearing side perpendicular to E field, the magnetic resonance exhibits red/blue shift as…
