| titleOfInvention | Planar antenna |
| abstract | The present invention provides a planar antenna. A multi-layered dielectric substrate is separately printed with different conductor circuits which, after compression, form two radiation units. The two radiation units are separately operated at two different working frequency bands, wherein the first radiation unit is produced by separately forming different conductor circuits on the substrate of each layer, and using an interlayer conducting means to form a 3-D twisted antenna; and the second radiation unit is constituted by an L-shaped conductor circuit, one end of which being connected to one end of the first radiation unit to form a common feed end. Through the above-mentioned dual-frequency antenna design, the circuit length and width of the first radiation unit and the circuit length of the second radiation unit can be suitably adjusted in order to obtain a desired resonant frequency and a desired frequency ratio. |
