2.4G 2dBi FPC Patch Antenna with 100mm Ø1.13 I-PEX
This mini low-profile FPC antenna is based on smart TheStripe™ antenna technology. It consists of FPC antenna and mini coaxial cable. Many module manufacturers specify peak gain limits for any antenna connected to the module. These peak gain limits are based on free space conditions. In fact, the peak gain of the antenna tested in free space is likely to be reduced by at least 1 or 2dBi when the antenna is placed inside the device.
Therefore, ideally you should choose a slightly higher peak gain antenna to compensate for this effect, resulting in better performance. By testing any of our antennas with your equipment and the appropriate layout, integration techniques or cabling, Keesun can ensure that the peak gain of any of our antennas will be below the peak gain limit. Keesun can then issue specifications and/or reports for the antenna selected in your device, clearly showing compliance with peak gain limits to ensure you meet regulatory requirements for that module.
For example, a module manufacturer may specify that the peak gain of the antenna must be less than 2dBi, but you do not need to select an embedded antenna with a peak gain of less than 2dBi in free space. This will give you a less optimal solution. If available, it is better to choose a slightly higher free space peak gain of 3dBi or higher. Once this antenna is integrated into your device, performance will fall below this 2dBi peak gain due to the effects of the GND plane, surrounding components, and the device housing. If you want to be absolutely sure, you can contact Keesun and we will test it.
Selecting a Keesun antenna with a peak gain higher than specified by the module manufacturer and seeking our help will ensure you get the best performance without exceeding the peak gain limit. Cables and connectors are customizable.
