SPE-12-8-137/E/OH Page 1 of 14 US Patent #9214732 SPECIFICATION Patent Granted FXP74 Black Diamond 2.4GHz Band Antenna Part No. : FXP74.07.0100A Product Name : FXP.74 Black Diamond 2.4GHz Antenna Feature : 4dBi Peak Gain Flexible, Ultra Low Profile IPEX MHF I Connector (U.FL compatible) 100mm 1.13 Mini-Coaxial Cable 47*7*0.1 mm RoHS Compliant
SPE-12-8-137/E/OH Page 2 of 14 US Patent #9214732 1. Introduction The FXP.74 Black Diamond is a small ultr a-low profile antenna for 2.4 GHz band that includes Bluetooth, Zigbee and Wi-Fi single band application. The FXP. 74 has a peak gain of 4dBi at 2.4GHz and efficiencies of above 50%. This Taoglas patent granted antenna is unique in the market with exceptionally stable performance different applications. It is made from a flexible polymer, has a tiny form factor (14mm*7.0mm*0.1mm) and has double-sided 3M tape for easy and robust “peel and stick” mounting. The FXP.74 is the ideal all-round antenna solution for fitting into narrow spaces and still maintaining high performance, for example on the inside top or adjacent side applied directly to the plastic housing of LCD monitors, tablets, smartphones, small AP routers, etc. 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 sli ghtly 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 c able, 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 yo u can be assured you are meeting regulatory requirements for that module.
SPE-12-8-137/E/OH Page 3 of 14 US Patent #9214732 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.
