Integrated dual-band printed monopole antenna

摘要

An integrated dual-band printed monopole antenna includes a microwave substrate, a first dual-band monopole antenna, a second dual-band monopole antenna and a ground plane. The substrate has a first surface and a second surface. The first and the second antennas are disposed on the first surface of the substrate and each is excited by a first or a second microstrip feeding line through a first or a second feeding port. The first and the second dual-band monopole antennas both include a first horizontal radiating metallic line, a second horizontal radiating metallic line and a vertical radiating metallic line. The vertical radiating metallic line has a feeding point in one end connecting to the first or the second microstrip feeding line. The ground plane is disposed on the second surface of the substrate, wherein the ground plane has a main ground plane and a protruded ground plane extending between the first and the second antenna.
