GW.05.0153 Datasheet, PDF (2/39 Pages) Taoglas antenna solutions – Max Peak Gain compliant with most WiFI modules

1. Introduction
The GW.05 dual band WiFi Hinged Rotatable Antenna is a high efficiency monopole
antenna. Compared to other much larger antennas on the market, it has superior
wide-band high efficiency characteristics. The bright green colour of the antenna adds
a unique quality look and feel to any modern WiFi application point, device or router.
It also provides differentiation if using Taoglas other similar looking antennas (such as
the black color Taoglas TG.09 cellular antenna) on same device. The connector used is
Rev SMA(M), the standard mating part for an antenna to most WiFi application points
and routers in the market.
The GW.05, as all monopole antennas, works best connected directly to the
ground-plane of the device main PCB or to the outside of a metal housing. However it
still has very good performance (>50%) even without connecting to a ground-plane,
making it the best all round small WiFi terminal antenna on the market.
In the un-grounded installation condition it also comes below the max peak gain
requirements for most WiFi modules which are usually 2dBi, so it can comply with FCC
regulations.
The GW.05 is for Wi-Fi, WLAN, Zigbee, Bluetooth, and 802.11a/b/g/n/ac applications.
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.
