SPECIFICATION PATENT PENDING Part No. : FXP840.07.0055B Product Name : FXP840 Freedom Series Super Small Monopole Dual-band 2.4 GHz and 4.9-6GHz Antenna Features : Flexible and Tiny - Ultra Low Profile 14mm*5mm*0.1mm 2dBi Peak Gain Adheres directly inside of product plastic or glass housing Form factor and cable routing convenient for integration IPEX MHF1 Connector (U.FL compatible) 55mm Ø 0.81mm mini-coaxial cable Customizable cable and connector RoHS Compliant SPE-12-8-115/F/EZ Page 1 of 15 1. Introduction The patent pending FXP840 is a super small monopole ultra-low profile antenna for 2.4/4.9-6 GHz. This antenna is designed for DSRC, V2V, WiFi, Bluetooth, ZigBee and other applications in these bands. The FXP840 has a peak gain of 2.5dBi at 2.4GHz and efficiencies of 40%, and 2.5dBi gain and 53% efficiency at 5.8GHz. This Taoglas patent pending antenna is unique in the market because it is made from polyflexible material, has a tiny form factor (14mm*5.0mm*0.1mm) 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 FXP840 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. The cable and connector are customizable according to customer requirements. 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 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 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.
