Specification Part No. : CA.14 Model : 2.4GHz High Efficiency Ultra-Small Chip Antenna Description : 2400MHz to 2500MHz WLAN/WIFI/Bluetooth/Zigbee Features : 3*3*1mm Smallest size Peak Gain 1dBi 50 Ohm Impedance RoHS SPE-12-8-002/A/SS Page 1 of 7 1. Introduction The CA.14 2.4GHz chip antenna is developed for mobile devices and modules for very small space requirements for WLAN, Zigbee and Bluetooth applications. At 3mm*3mm*1mm it is one of the smallest antennas available worldwide. 2.0 Key Performance Indicators CA.14 is designed to mount at the edge of an evaluation board of 45*45mm, as shown in the photo. The antenna performance was measured with the CA.14 mounted on the evaluation board with SMA connector.
