SAM-3533532005-KF-L1

Rev 2.0

Description:
Model SAM-3533532005-KF-L1 is a linear polarized, 35
GHz microstrip patch array antenna. The antenna
implements a series-fed power distribution to achieve
low side lobe levels. The antenna has a gain of 20 dBi anda beamwidth of 15 degrees vertically and 4.8 degrees
horizontally, with a better than 18 dB side lobe
suppression level. The antenna is constructed with a highperforming, low loss soft microwave substrate to achieve
the best performance in the class. The RF interface is afemale 2.92 mm connector. A standard WR-28
waveguide version with a UG-599/U flange is offeredunder model number SAM-3533531905-28-L1.
