1. Introduction
The FXP831 is a high efficiency, small, dual-band, dipole antenna for 2.4/4.9-6GHz
band including WiFi, Bluetooth, Zigbee, DSRC, V2V, and other applications in these
bands. The FXP.831 has a peak gain of 2.5dBi at 2.4GHz and efficiencies of 56%, and
4.5dBi and 55% along bands 4.9GHz to 6GHz.
This Taoglas patent pending antenna is unique in the market because it is made from
poly-flexible material, has a tiny form factor (45*7*.01mm) 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 FXP.831 is the ideal all-round antenna solution for squeezing 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 devices.
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
SPE-11-8-026/G/SS Page 3 of 19
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.
