This antenna is perfect for use together with our Lora as well as our SubGHz boards. It is a 43.5mm by 20mm flex PCB antenna with double-sided tape on the backside, making it perfect for mounting inside an enclosure. It has been designed specifically to be attached to a plastic wall of around 1.5mm’s to 2.0mm’s thickness. In open air, it does not perform as well as when it has been mounted properly.
The antenna cable is a 110mm long, 1.13mm OD 50ohm coaxial cable that is soldered onto the antenna. The other end of the cable is terminated with a 50-ohm IPEX connector that attaches directly to our LoRa and SubGHz boards.
The back of the antenna is lined with a 3M (300LSE) double-sided adhesive, which makes it super easy to attach the antenna to the inside of your product enclosure.
