Abstract
A broadband antenna structure has an electrically conductive enclosure with a closed end, over which a non-electrically conductive cover is placed. A radiating portion of an antenna feed layer comprising a conductive patch antenna element is placed in between the enclosure and the cover. The patch antenna element design is inherently broader band than that of conventional cavity-backed slot-radiating antennas, which are constrained in bandwidth by the need to keep the cavity formed in the enclosure small. The dielectric constant of the dielectric material of the cover reduces the required size of the conductive antenna element. The broadband antenna structure may be connected with an electronic device to form an antenna arrangement in which a portion of the antenna feed layer extends through an opening in a surface of an antenna housing, the portion being within an electronic device enclosure of the electronic device.
