Abstract
A mobile wireless terminal includes a housing, a cover removably attached to the housing, and an antenna device disposed inside the housing. The antenna device includes a first antenna element that is disposed inside the housing and serves as a feed element, a plate that provides a ground plane for the first antenna element, and a second antenna element that is formed on one surface of the cover so as to face the first antenna element with the cover being attached to the housing and capacitively couple to the first antenna element and that serves as a parasitic element.
