The present invention provides a feed circuit capable of enhancing a mechanical strength and electrical characteristics thereof. A waveguide is provided on a plate-like member, and has a plurality of branches. A bridging part-extends in a Y direction intersecting an X direction in which the waveguide-guides an electromagnetic wave between sidewalls of the waveguide (14), and includes a plurality of members provided at predetermined intervals in the X direction so that intensity of a reflected wave becomes a predetermined intensity or less.

An antenna includes a conductor plate, for example. The conductor plate has a slot and a branch slot, wherein the branch slot has one end connected to the slot and another end which, when viewed from the one end, extends along the slot in an antinode direction of an electric field at the lowest-order resonant frequency of the antenna, and is closed in the conductor plate.

A device includes a display and a housing. The housing at least partially surrounds the display. The housing includes a first housing segment defining at least a first portion of an exterior surface of the device and a first interlock feature having an interlock surface that is offset with respect to an end surface of the first housing segment. The first interlock feature has a first opening formed in the interlock surface. The housing further includes a second housing segment defining at least a second portion of the exterior surface of the device and a second interlock feature having a second opening aligned with the first opening, and a non-conductive housing component defining a third portion of the exterior surface of the device and extending into the first opening and the second opening.
