This invention discloses a dual-band monopole antenna, which can be operated in dual bands and easily tuned to the frequency band required for WLAN system by means of adjusting the frequencies of the resonant mode of the antenna. The dual-band monopole antenna of the invention mainly includes a microwave substrate having a first surface and a second surface, a first horizontal radiating metallic line, a second horizontal radiating metallic line, a vertical radiating metallic line, a feeding point, and a ground plane. The microwave substrate includes a first surface and a second surface. The first horizontal radiating metallic line is printed on the first surface. The second horizontal radiating metallic line is printed on the first surface. The vertical radiating metallic line is printed on the first surface, wherein the first horizontal radiating metallic line and the second horizontal radiating metallic line respectively intersect the vertical radiating metallic line at different positions. The feeding point is disposed on the vertical radiating metallic line, and a ground plane is printed on the second surface of the microwave substrate.

Dual-band monopole antenna

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.

Integrated dual-band printed monopole antenna
