A radiating portion of the antenna feed layer comprising a conductive patch antenna element is placed in between the enclosure and the cover. This 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, so that the column elements may be arranged in an array at substantially half-wavelength spacing. The new design suffers less compromise in terms of bandwidth in achieving the same size constraint.

20130207852ANTENNA APPARATUS AND COMMUNICATION TERMINAL - In an antenna apparatus, on an undersurface of a metal cover, a feeding coil module is disposed. In a casing, a printed circuit board is included. A ground conductor, a feeding pin, and a ground connection conductor are disposed on the printed circuit board. When the metal cover is mounted on the casing, the feeding pin is in contact with a connection portion of the feeding coil module and is electrically connected thereto. The ground connection conductor is in contact with the metal cover and connects the metal cover to the ground conductor. The ground connection conductor is disposed at either side of a slit outside an area in which the current density of an induced current flowing through the metal cover is in a range from a maximum value to approximately 80% of the maximum value or one side of the slit in the area.08-15-2013
20130207853ANTENNA SYSTEM FOR WIRELESS TERMINAL DEVICES - An antenna system suitable for a mobile device is disclosed. The mobile device includes a display casing with a conductive region and a non-conductive region. The antenna system includes a driven element having an inverted-F antenna arranged in the non-conductive region of the display casing. The display casing is also provided with an electrostatic discharge (ESD) conductor as a countermeasure against ESD. The ESD conductor is connected to the conductive region of the casing. The ESD conductor causes static charges in the air to be discharged to the conductive region of the casing. The ESD conductor also produces harmonic resonance and exchanges electromagnetic energy with the driven element to improve the gain of the driven element.08-15-2013
