SAM-3934030695-2F-L1-4C

Ka Band Microstrip Patch Array Attenna, 39 Ghz, 6 dBi,
50° x 95°
SAM-3934030695-2F-L1-4C is a linear polarized, 39 GHz microstrip
patch 1 x 4 array antenna. The antenna array implements four individual
antenna ports so that beamforming can be achieved via various input
signal definitions. The individual patch antenna has a gain of 6 dBi and atypical vertical beamwidth of 50 degrees and horizontal beamwidth of 95
degrees respectively. The combined gain and beamwidth of the array are12 dB and when the array is fed with equal amplitude but 180° out-ofphase signals at two sides. The antenna is constructed with a highperforming, low loss soft microwave substrate to achieve the best
performance in the class. The RF interface is four 2.4mm (F) coaxial
connectors. Other interface, such as K(F) connectors are offered undervarious model numbers.
