23 dBi Gain, 33.8 to 36.2 GHz, K(F) Connector, Ka Band Integrated Substrate Waveguide Array Antenna
Model SAI-3433632310-KF-C1 is a right-handed, circular polarized integrated substrate waveguide array antenna covering the frequency range of 34 to 36 GHz. The antenna takes advantage of the low loss nature of the waveguide and printed circuit manufacturing process to offer high performance and loss cost solutions. The antenna implements a series-fed power distribution to achieve low sidelobe levels. The gain of the antenna is 23 dBi and the beamwidth is 10° vertically and 4° horizontally, with a typical sidelobe suppression of -15 dB. The antenna shows close to 50% antenna aperture efficiency and the highest gain in the class. In addition, the antenna shows good return loss and up to 7% bandwidth. The RF interface is a standard female 2.92 mm connector, however, a WR-28 waveguide is offered under a different model number.
