For a given frequency, what is the effectiveness of a larger sensor compared to a smaller one?

A larger sensor is able to receive signals more effectively than a smaller one due to its increased surface area, which allows it to capture more electromagnetic energy or signals in its environment. This characteristic enhances the signal-to-noise ratio, improving the sensor's overall performance in detecting and processing signals, especially in challenging conditions where signal strength may be weak. The larger size also aids in better resolution and sensitivity, allowing for more accurate data collection and analysis.

In contrast, while smaller sensors may be more compact, their limited surface area can restrict their ability to gather the same amount of signals. This can lead to diminished effectiveness, particularly when operating in environments with lower signal levels, as they might struggle to compete with the increased performance that larger sensors provide.
