SAM-5735930395-15-L2-4W

V Band Microstrip Patch Array Attenna, 58 Ghz, 4 dBi,
50° x 95°
SAM-5735930395-15-L2-4W is a linear polarized, 58 GHz microstrip
patch 2 x 2 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 typical gain of 4dBi, a vertical beamwidth of 50 degrees and horizontal beamwidth of 95
degrees, respectively. When all ports are fed with in-phase and equalamplitude signals, the combined gain and beamwidth of the array are 12dBi and 40 degrees, typically. 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 WR-15 waveguides
with UG-385/U compatible flanges.
