ABSTRACT:
A wireless device has a housing, a patch antenna, and an open/shut sensing unit which senses the open/shut state of the housing and forms an open/shut signal indicating the open/shut state. The patch antenna has a first element which corresponds to a first polarized wave, a second element which corresponds to a second polarized wave and is to be added to the first element, and a switching unit. The switching unit disconnects and connects the second element from and to the first element based on the open/shut signal to make the patch antenna suitable for the first or second polarized wave.
