The CA.25 is a super small SMT ceramic loop antenna for 2400MHz to 2500MHz/ 5150MHz to 5850MHz dual band that includes Bluetooth, WIFI, Zigbee, and ISM applications. The CA.25 has a peak gain of 1.0 dBi and 1.5 dBi at 2.4GHz and 5.5GHz, respectively, with an efficiency of at least 60%. This antenna is delivered on tape and reel. The CA.25 antenna has an ultra-low profile form factor of 3.05mm x 1.6mm x 0.55mm and allows use on extremely thin devices while still maintaining excellent RF performance characteristics. All that is needed is a 50 Ohm transmission line to the module.
