Abstract

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.
