LA.02 2.4GHz Embedded Loop Chip Antenna
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.

For example, a module manufacturer may state that the antenna must have less than 2dBi
peak gain, but you don’t need to select an embedded antenna that has a peak gain of less
than 2dBi in free-space. This will give you a less optimized solution. It is better to go for a
slightly higher free-space peak gain of 3dBi or more if available. Once that antenna gets
integrated into your device, performance will degrade below this 2dBi peak gain due to the
effects of GND plane, surrounding components, and device housing. If you want to be
absolutely sure, contact Taoglas and we will test. Choosing a Taoglas antenna with a higher
peak gain than what is specified by the module manufacturer and enlisting our help will
ensure you are getting the best performance possible without exceeding the peak gain limits.
