GWLA01 Datasheet, PDF (4/21 Pages) Taoglas antenna solutions – GPS L1/GALILEO & Bluetooth/Wi-Fi 2.4GHz

For example, a module manufacturer may state that the antenna must have less than
2 dBi peak gain, but you don't need to select an embedded antenna that has a peak
gain of less than 2 dBi 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 3 dBi or more if available.
Once that antenna gets integrated into your device, performance will degrade below
this 2 dBi 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.
