SAM-1431430695-SF-L1-8C

Ku Band Microstrip Patch Antenna, 14 GHz, 6 dBi,
50° x 95°
SAM-1431430695-SF-L1-8C is a linearly polarized, 1 x 8, 14 GHz
microstrip patch antenna. The antenna implements eight 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 are
15 dBi and 8 degrees when the array is fed with equal amplitude andphase signals. The antenna is constructed with a high performance, lowloss soft microwave substrate to achieve the best performance in theclass. The RF interface is eight SMA (F) coaxial connectors. Otherinterfaces such as K (F) connectors, are offered under various modelnumbers.
