Switching a slot antenna

摘要

A computing device may include a conductive member, a slot antenna having a slot defined by the conductive member and an antenna pattern portion disposed proximate to the slot, and/or a slot switch configured to switch a portion of the slot. The slot switch may have a first terminal and a second terminal such that the portion of the slot is disposed between the first terminal and the second terminal. The slot switch may be switchable between a first configuration in which the first and second terminals are electrically connected and a second configuration in which the first and second terminals are not electrically connected. The computing device may also include a switching controller configured to switch the slot switch between the first and second configurations.

主权项

1. A computing device comprising:
a conductive member; a slot antenna including a slot defined by the conductive member, and an antenna pattern portion disposed proximate to the slot; an excitation point configured to transfer wireless signals between the slot antenna and a transceiver circuitry of the computing device, the excitation point being coupled to a portion of the antenna pattern portion; a first slot switch configured to switch a first portion of the slot, the first slot switch having a first terminal and a second terminal such that the first portion of the slot is disposed between the first terminal and the second terminal, the first slot switch being switchable between a first configuration in which the first and second terminals are electrically connected and a second configuration in which the first and second terminals are not electrically connected; a second slot switch configured to switch a second portion of the slot, the excitation point being disposed between the first slot switch and the second slot switch; and a switching controller configured to switch the first slot switch between the first and second configurations and switch the second slot switch.
