1. Introduction

The LA.02 is a 2.4GHz embedded loop chip antenna that has best in class efficiency, 66% on

center frequency. It’s a miniature SMD ceramic component, designed to be mounted directly

on the edge of the main device PCB and is suitable especially for very small space

requirements for Bluetooth LE, Wi-Fi, 802.11 applications. The LA.02 uses this main PCB

ground plane to increase antenna efficiency, requiring minimum ground-clearance around the

antenna. The opposite side of the board on which the antenna is mounted does not need

ground-clearance, allowing more space for components or signal routing. This antenna is

delivered on tape and reel.

Typical applications

- Telematics devices

- Bluetooth LE Wearables

- Bluetooth Headsets

- 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

Some frequency offset may happen as is normal with antennas embedded devices, so the

antenna can be tuned for different PCB sizes and enclosures by simply changing the value of

the matching circuit. Please contact your regional Taoglas sales office for support.

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 of our antennas’ peak gain will be

below the peak gain limits. Taoglas can then issue a specification and/or report for the

selected antenna in your device that will clearly show it complying with the peak gain limits,

so you can be assured you are meeting regulatory requirements for that module.
