QUESTION

asked by
Antenna efficiency without a matching circuit
Hello,

I am planning to use a M10578-A3 module with the SR4G013 antenna on a wearable device. I was wondering if it would be necessary to make a matching circuit or not. Would the efficiency decrease that much without it, or is it still usable? (Note: The device does also have an LTE module).

Thank you very much

Hi,

The matching circuit is required as the frequency of the antenna will be shifted depending on how it is implemented and the antenna surrounding. The matching circuit would tune the frequency back to the desired band.
