Product overview
The Shenzhen JND Technology Co., Ltd JND ST-38-AGH2 is a portable active GNSS antenna intended for trackers, navigation equipment and autonomous vehicles. Its physical architecture uses a single feed pin to produce two frequency modes, supporting a simple motherboard footprint and a low-cost integration approach. The antenna combines right-hand circular polarization with a low axial ratio. Its patch-element operating range can be selected according to customer requirements, making that selection a relevant procurement configuration detail.
The stated frequency coverage includes GPS L1, L2 and L5 alongside BeiDou B1 and B2 within the antenna’s dual-band design. The active RF section uses an LNA + DualSAWSAW + PD + LNA arrangement to improve GNSS RF sensitivity and signal-to-noise ratio, with constant high gain across the full frequency band. A female SMA output provides the connection to an RF cable. The product is an antenna component for integration into positioning equipment.
