page 2 of 10 the fxp75 atom is a super small monopole ultra-low profle antenna for 2.4ghz band that includes bluetooth, wi-fi, zigbee and ism bands application. the fxp75 has a peak gain of 2.5dbi at 2.4ghz and effciencies of 45%. this taoglas patent pending antenna is unique in the market. two years of constant research and development have created the worlds smallest coax cabled true 2.4ghz antenna. made from poly-fexible material, the antenna has a tiny form factor of 5.9*4.1*0.24mm and has double-sided 3m tape for easy peel and stick mounting. the cable routes conveniently directly out of the bottom of the antenna, reducing the volume the antenna takes up in the device to an absolute minimum compared to other designs. the fxp75 is the ideal all-round antenna solution for ftting into narrow spaces and still maintaining high performance, for example in a bluetooth earphone where metal and electrical noise degrades onboard smt antenna performance. the fxp75 is small enough to be routed away from metal and electrical noise to deliver much improved range and reliable sound quality in bluetooth earphones. due to the potential for detuning in a tiny device environment, taoglas recommends that you contact us at our regional sales offce for integration support and testing and optimization of the antenna in your device before going to production. 1. introduction spe-13-8-067/a/ez |
