Chapter 10 large loop antennas
WebSep 19, 2024 · Small loops and full-wave loops are very different antennas. There isn't a well-defined distinction between "small loops" and "large loops", but a typical rule of thumb is a loop is "small" when its diameter is less than 1/10th of a wavelength. WebAbstract: Near-field antennas have been applied in a number of short-range wireless systems, including near-field communication (NFC), radio-frequency identification (RFID), wireless power transfer, wireless charging, medical hyperthermia and imaging systems, antenna measurement systems, and so on.

Weblarge loop antenna is that the shape is not important. As long as the perimeter of the antenna is approximately 1 wavelength, the loop antenna will produce a radiation pattern very similar to the one shown above. The shape of the loop may be circular, square, triangular, rectangular, or any other polygonal shape.
