Fresnel Zone Antennas
hi, mmwave
i am interested in TSA (Tapered Slot Antenna), generally TSA is a broadband and endfire antenna.
i do not know how to feed teflon lens to get narrow beam on your antenna.
how about use fresnel zone plate lens antenna or fresnel zone plate reflectarrays
if your application is not wideband in Ka or V-band?
here is one example,
Printed Millimeter-Wave Reflectarrays

and anybody who has more information about Fresnel Zone Antennas,
please let me know.
thanks,
