spe - 11 - 8 - 04 9/d /wy page 2 of 9 1 . overview t he fxp73 blue diamond 2.4ghz antenna works on wi fi, zigbee, bluetooth and ism band at 2.4 ghz. this antenna has been designed with a specific solution to cover the current market applications that require rectangular form - factor , with easy installation thr o u gh a cable connection. many module manufacturers speci fy 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 devic e. 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 appropriat e 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 compl ying 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 dont need to select an embedded anten na 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, performan ce 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 spec ified by the module manufacturer and enlisting our help will ensure you are getting the best performance possible without exceeding the peak gain limits.
