Introduction
The WLA.10 2.4 / 5.8 GHz Loop antenna is a high efficiency, miniature SMD, edge mounted ceramic antenna
for Dual-band 2.4 / 5.8 GHz Wi-Fi and 802.11 applications where PCB space is limited, such as hand-held
devices. The WLA.10 uses the main PCB as its ground plane, thereby maintaining good efficiency despite its
small size. The efficiency is very stable on the complete bandwidth of both lower and upper bands allowing
for maximum data throughput rates on all channels available.
Introduction
The WLA.10 can be tuned for different PCB sizes/environments by simply changing the values of the matching
circuit. Multiple WLA.10 antennas can be integrated easily on a board to achieve excellent MIMO throughput.

Introduction
The results below are based on a 80mm x 40mm ground-plane. If your ground-plane is smaller the efficiency
will decrease.

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 2 dBi 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 2 dBi peak gain, but
you don't need to select an embedded antenna that has a peak gain of less than 2 dBi 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 3 dBi or more
if available. Once that antenna gets integrated into your device, performance will degrade below this 2 dBi
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.
This antenna can be mounted with no performance degradation in either orientation as long as the antenna
is soldered correctly via Surface mounting. Please see the integration instructions section for further detail
regarding the optimum way to integrate this antenna into your device. For further information please contact
your regional Taoglas customer support team.
