1. Overview
The FXP72 Freedom 2.4GHz Antenna works on WiFi, ZigBee, Bluetooth and ISM band
at 2.4GHz. This antenna has been designed with a specific characteristic of having a
ground coupling effect in between the antenna and the device’s board, suitable for
those devices where there is no clearance in between the enclosure and the board,
keeping the antenna performance. The Antenna can be placed above or below of the
device’s board, but leaving the radiated elements of the antenna free of metal. This
design can work on different thickness and plastic materials. We have selected a piece
of ABS plastic with 1.5 mm of thickness for testing.
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
