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.
