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.
