WLA.10

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. 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. At 3.2mm*1.6mm*0.5mm, the WLA.10 is one of the smallest antennas available worldwide. This antenna is delivered on tape and reel.
 

Typical applications:

• Dual-band Wi-Fi Communications
• Handheld Devices
• IEEE 802.11 b/g/n/ac
• Tablet PCs
• Specialized Control Systems
• Wireless Remote Controls

The results below are based on an 80mm x 40mm ground-plane. If your ground plane is smaller the efficiency will decrease. Contact a Taoglas regional office near you for optimization services. Many module manufacturers specify peak gain limits for any antennas that are to beconnected to that module. Those peak gain limits are based on free-space conditions. Inpractice, the peak gain of an antenna tested in free-space can degrade by at least 1 or2 dBi when put inside a device. So ideally you should go for a slightly higher peak gainantenna 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 appropriatelayout, integration technique, or cable, Taoglas can make sure any of our antennas peakgain will be below the peak gain limits. Taoglas can then issue a specification and/orreport for the selected antenna in your device that will clearly show it complying with thepeak 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 dont 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. Ifyou 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.
