SPECIFICATION Part No. : CA.25 Product Name : 2.4/5 GHz Dual-Band Wi-Fi Dielectric Loop Antenna Feature : Smallest 2400MHz to 2500MHz/5150MHz to 5850MHz Dual-Band SMT Type Antenna Ultra Low profile 3.05mm x 1.6mm x 0.55mm Supports IEEE 802.11 a/b/g/n and ac Dual-Band WIFI systems Linear Polarization Tuned on 40*80mm ground plane RoHS Compliant SPE-15-8-005/B/WY Page 1 of 24 1. Introduction 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. Typical applications include: USB dongles Tablets Home and industrial in-wall WIFI automation Hand-held devices Many module manufacturers specify peak gain limits for any antennas that are to be connected to that module. Those peak gain limits are based on free- space conditions. In practice, the peak gain of an antenna tested in free-space can degrade by at least 1 or 2dBi when put inside a device. So ideally you should go for a slightly higher peak gain antenna than mentioned on the module specification to compensate for this effect, giving you better performance. Upon testing of any of our antennas with your device and a selection of appropriate layout, integration technique, or cable, Taoglas can make sure any SPE-15-8-005/B/WY Page 2 of 24
