1 Introduction
The GW.26 HT series 2.4 GHz Monopole SMA (M) mount antenna is ideal for 2.4 GHz wireless
applications such as Wifi, Zigbee and Bluetooth.
Antenna housing is made of highly resistant Dupont® Hytrel® TPEE material which is durable
in high temperature application environments up to 150°C. This material is often applied in
automotive or industrial applications, where the antenna is placed near the engine or heat
generating components.
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.
Connection is made via a fixed SMA(M) connector with a hardened TPEE casing, this antenna
is the ideal Wi-Fi-Bluetooth-ZigBee antenna for M2M devices where the antenna must be
placed in harsh high temperature environments.
