ABSTRACT:
Provided is a small monopole antenna having a loop feeder. The small monopole antenna having a loop feeder includes: a loop element forming a loop along a predetermined plane and having a loop feeder at the center thereof; a non-feeding type monopole antenna element including one end connected to a wire of the loop element and other end connected to a ground unit by being bended at the center of the loop element; a ground unit for grounding other end of the non-feeding type monopole antenna; and a first connecting unit for connecting the non-feeding type monopole antenna to an external device for feeding the loop feeder of the loop element through the non-feeding type monopole antenna.
