Abstract
Official abstract text for this publication.
A wireless communication device includes a base board, a metal zone, and a filter. The metal zone and the filter are disposed on the base board. The metal zone defines a slot. The filter is connected to the slot to divide the slot into a first slot section and a second slot section. When a current having a first frequency flows through the first slot section and the second slot section, the filter is in an open circuit state, and the first slot section and the second slot section are activated to receive/transmit wireless signals having a first central frequency. When a current having a second frequency only flows through the first slot section, the filter is in a closed circuit state, and the first slot section is activated to receive/transmit wireless signals having a second central frequency.
