The KSF410.A from Taoglas is a 28 GHz 5G mm-wave beam-steering antenna with a sixteen-element linear phased-array. It delivers a gain of up to 17 dBi and has a wide 3dB beamwidth for wide angular coverage in azimuth, with most of the energy focused within 45° of the main beam. The antenna employs beam steering/forming at the RF level using RF phase and amplitude shifters, or beam forming networks. Antennas in the array are grouped in groups of four, each group with Integrated circuit (IC) Phase shifter, LNA and Power amplifier (PA) allowing field of view (FoV) of ±45°.
The KSF410.A uses a Ka-Band 5G chipset that supports four Tx/Rx radiating elements, includes all requisite beam steering controls for 5 bit phase and gain control, and operates in half duplex fashion to enable a single antenna to support both Tx and Rx operation. The provided SPI interface allows direct access to chipset to control the device configuration. The antenna has up-to 2GHz impedance bandwidth, which gives upwards of 2Gbps data rates which is well suited for fixed and mobile broadband capacity hungry Next Generation Networks. It also features higher than 20 dB cross pol rejection making it less susceptible to interference from undesired signals.
The antenna can be directly connected using standard 2.92mm and SMPM connectors. It is ideal for use at User Equipment for client-side integration or inside a Ka band 5G Access Point (AP). The application can be for indoor and outdoor wireless coverage for mobile or fixed broadband access in 5G Routers and/or APs. There is also an option to use a coaxial to waveguide adaptor in conjunction with Ultra Low Loss Pre-Connectorized Cables.
