1. Introduction
The GW.15 2.4GHz dipole SMA terminal mount antenna is ideal for 2.4GHz wireless
applications such as Bluetooth and Wireless LAN. At only 108mm in length, an omnidirectional 3dBi gain across all bands ensures constant reception and transmission. The
antenna structure is designed for robust handling and the housing is made with TPU giving
superior environmental reliability and a quality finish. The antenna can be rotated 90 degrees
on the base hinge for ease of placement.
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. It is better not to select an embedded antenna with very low
free-space peak gain (
