Product Description
Technical Details
This PCB antenna is designed for 2.4 GHz WiFi and BLE applications in compact devices. It is intended for developers and device builders who need an internal antenna for WisDuo- or WisBlock-based IoT hardware.
The version described here is the MHF1 variant only. It is compatible with the WisDuo module RAK4630 and the WisBlock Core module RAK4631. Other connector variants or module groups are outside the scope of this listing.
Its slim form factor and adhesive backing make it easy to mount inside an enclosure. That works well in sensor nodes, battery-powered wireless devices, and compact embedded systems where no external antenna is planned and internal space is limited.
The antenna operates in the 2400 to 2500 MHz range and is built for omnidirectional performance. That makes it suitable for WiFi and Bluetooth Low Energy links in small IoT devices that need a low-profile internal antenna.
