1. Introduction
The WLA.01 2.4GHz Loop antenna is a high efficiency miniature SMD edge mounted ceramic antenna for
very small space requirements for Wi-Fi, WLAN, Zigbee, Bluetooth and 802.11 applications. The WLA.01
uses the main PCB as its ground plane, thereby increasing Antenna Efficiency. It is tuned for different
PCB sizes by simply changing the value of the matching circuit. At 3.2mm*1.6mm*0.6mm, the WLA.01 is
one of the smallest antennas available worldwide. This antenna is delivered on tape and Reel.
1.1 Applications
2.0 Key Performance Indicators
WLA.01 is designed to mount at the centre point of the edge of an evaluation board of 80 x 40mm.The
antenna performance was measured with the WLA.01 mounted on the evaluation board with SMA(F)
connector.
* Center frequency will be offset to working frequency according to the conditions of user’s Ground
plane and radome.
**The data was measured by A Test Lab Techno Corp. (CTIA Authorized Test Lab).
*Bluetooth earphone systems
*Hand-held devices when Bluetooth/Wi-Fi functions are needed, e.g., Smart phone.
*IEEE802.11 b/g
*ZigBee
*Wireless PCMCIA cards or USB dongle
