摘要： A dual-band dipole antenna is provided with a first conductor arm, a second conductor arm, and a feeding signal line, wherein two conductor arms have different lengths. The feeding signal line has a signal end and a ground end, respectively connected to the feeding points on the two conductor arms. The feeding signal line transmits feeding signals to the two conductor arms through the feeding points, thereby generating two operating modes of the antenna. The desired frequency ratio of a second operating mode and a first operating mode for a dual-band wireless local network is achieved by simply changing the two conductors' relative lengths, so that the frequency ratio of a second operating mode and a first operating mode for the antenna is the same as the desired frequency ratio.

摘要： A dual-frequency planar antenna disclosed herein utilizes a main radiating device to produce a resonance mode and excites a parasitic radiating device to produce another resonance mode by the coupling of energy. These two modes can provide sufficiently broad bandwidths, and the present invention is simple in design, which makes it cost effective. Therefore, the planar antenna of the present invention is a competitive alternative for wireless communication applications.

摘要： A planar inverted-F antenna with a first operating bandwidth and a second operating bandwidth comprises a ground surface, a radiating device, a shorting device, a dielectric material, and a feeding device. The dielectric material is for isolating the radiating device from the ground surface. The feeding device is for transmitting a microwave signal. The radiating device further includes a first radiating element, a second radiating element, and a third radiating element. The first operating bandwidth is formed by the first resonance mode of the first radiating element and the second radiating element. The second operating bandwidth is formed by the second resonance mode of the first radiating element and the second radiating element and the first resonance mode of the third radiating element.
