WCM.01.0111 – 2.4GHz Wi-Fi Bluetooth Button Antenna


Smallest SMA(M) Wi-Fi Bluetooth Antenna in the IoT Market

The WCM.01 2.4GHz antenna is the smallest SMA(M) Wi-Fi Bluetooth antenna in the IoT market, fitting into spaces no other traditional monopole, dipole or rubber ducky antenna can go!

A unique PIFA design provides omnidirectional gain across the 2.4GHz to 2.5GHz range, ensuring constant reception and transmission for 2.4GHz Wi-Fi and Bluetooth applications.
This antenna features greater than 60% efficiency when connected directly to the ground plane of the device. A great performance for the smallest Wi-Fi and Bluetooth antenna.

Typical Applications Include:
– Application Points
– Routers
– IoT M2M devices
– Smart home applications

The WCM.01 antenna has an IP67 waterproof enclosure and comes with an SMA(M) connector, making it compatible with most Wi-Fi applications and routers on the market. An RP-SMA(M) version is also available. For ideal radiation, mount the WCM.01 clear of metal.

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 freespace conditions. In practice, the peak gain of an antenna tested in freespace 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 freespace. This will give you a less optimized solution. It is better to go for a slightly higher freespace 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.
