Abstract
A multiband antenna includes a feed unit, a transceiving unit, and a resonance unit positioned adjacent to but separate from the feed unit and the transceiving unit. When feed signals are input to the feed unit, the feed signals are transmitted to the transceiving unit to form current paths of different lengths, and the resonance unit is driven to resonate and generates additional current paths of different lengths. In this way, the transceiving unit and the resonance unit are enabled to respectively receive and send wireless signals of different frequencies, and thus the multiband antenna is capable of receiving and sending wireless signals in more than two frequency bands.
