Abstract
A multi-frequency antenna includes a ground layer, at least one antenna unit and at least one antenna network. The antenna unit has its one end electrically connected to the ground layer and its other end electrically connected to the antenna network for generating at least one first resonance frequencies. The antenna network includes at least one feeding circuit, and at least one resonance unit. Each resonance unit includes at least one resonant segment. Each resonant segment is electromagnetically coupled with the adjacent ground layer to generate at least one second resonance frequency. Thus, the multi-frequency antenna is capable of generating multiple different resonance frequencies.
