Antenna Array PCB


CHW1010-ANT1-1.0 Antenna Module

CHW1010-ANT1-1.0 is an antenna array consisting of eight dual polarized patch antenna elements. The antenna array PCB is intended for direction and positioning system solution providers.

The CHW1010-ANT1-1.0 antenna array board features a CHW1010 SP16T antenna switch, capable of controlling and sampling RF signals for Bluetooth® AoA and AoD technology. The device comprises of very low phase mismatch antenna switch array which enables real high accuracy positioning.

CHW1010-ANT1-1.0 antenna boards enable system solutions which are insensitive to multi-path signals, has position accuracy down to sub 0.5 meter level and are easy, fast and cost-efficient to manufacture.

CoreHW offers AoA demo systems with CoreHW firmware and Windows PC positioning engine software with user interface (GUI). The demo system contains four CHW1010-ANT1-1.0 PCB based locators. The demo system can be used for laboratory tests and for initial testing in real use case scenarios.
