868/915MHz flexible ISM band antenna
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 of 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 50ohm IPEX connector that attaches directly to our LoRa and SubGHz boards.
That 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.
