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.
