Antenna Array PCB


CHW1010-ANT3-1.0 Antenna Module

CHW1010-ANT3-1.0 is an antenna module consisting of four patch antenna elements. The antenna array PCB is intended for direction and positioning system solution providers.

CHW1010-ANT3-1.0 antenna array board contains CoreHW CHW1010 SP16T antenna switch, which can be used to control and sample RF signal for Bluetooth® AoA and AoD technology. The device comprises of exceptionally low phase mismatch antenna switch array which enables high accuracy positioning.

CHW1010-ANT3-1.0 antenna boards enable system solutions which are insensitive to multi-path signal and has outstanding position accuracy down to 50cm level.

CoreHW offers an AoA reference design system with CoreHW firmware and Windows PC positioning engine software with user interface (GUI). The reference system contains four patch antenna array-based locators. The reference system can be used for laboratory tests and PoC testing in real use case scenarios.
