GW260151 Datasheet, PDF (2/13 Pages) List of Unclassifed Manufacturers – 2.4GHz Miniature Screw mount Monopole Antenna
1 Introduction
The GW.26 2.4 GHz Monopole RP-SMA(M) mount antenna is ideal for 2.4 GHz wireless
applications such as Bluetooth and Wireless LAN.
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.
Connector mount is fully customizable.
