|20140159964||Antenna Device - An outer peripheral wall and an inner peripheral wall are formed in the lower part of a shark-fin antenna case. The lower end surface of the inner peripheral wall is bonded to the upper surface of an insulating base in an antenna base arranged on the lower surface of the antenna case. Thus, an antenna assembly can be housed in the antenna case which is constructed to be waterproof. The antenna assembly is provided with an element holder that is arranged upright on the antenna base; an umbrella-shaped element that is fixed to the top part of the element holder in such a way that the rear part thereof is positioned above the insulating base; an amplifier substrate for amplifying a reception signal of the umbrella-shaped element; and a coil that causes the umbrella-shaped element to resonate at the specified frequency.||06-12-2014|
|20140125550||ANTENNA DEVICE - The antenna device disclosed includes an insulating antenna case, an antenna base, an umbrella-type element, an amplifier substrate, and a coil. A lower surface of the insulating antenna case is open and a housing space is formed in the insulating antenna case. The antenna case is fitted on the antenna base. The umbrella-type element is provided on the antenna base. The amplifier substrate includes an amplifier which amplifies a signal received by the umbrella-type element, and is disposed on the antenna base. The coil is inserted between an output end of the umbrella-type element and an input end of the amplifier to make the umbrella-type element resonate at a predetermined frequency, and is disposed substantially at a center in a width direction of the umbrella-type element.||05-08-2014|
|20140125549||ANTENNA DEVICE - The antenna device disclosed includes an insulating antenna case, an antenna base, and an umbrella-type element. A lower surface of the insulating antenna case is open and a housing space is formed in the insulating antenna case. The antenna base includes an insulation base on which the antenna case is fitted, and a conductive base which is smaller than the insulation base and is fixed to the insulation base. The umbrella-type element is provided on the antenna base in such a way that a rear section thereof is located above the insulation base and a front section thereof is located above the conductive base.||05-08-2014|

|20130342405||Antenna Device - A low profile antenna device for use in a vehicle comprises a base unit, and an antenna unit. The antenna unit is supported on the base unit, and is provided with a first helical unit on the side near to the base unit, and a second helical unit on the side far from the base unit. The second helical unit is configured such that the surface area is larger per unit length than that of the first helical unit.||12-26-2013|
|20130176180||ANTENNA APPARATUS - An antenna apparatus that can suppress sensitivity degradation as much as possible to receive AM broadcasts and FM broadcasts even if an antenna height is decreased to 70 mm or less. An antenna board is vertically mounted on a planar antenna base, and a top portion is disposed to stride over the antenna board. An antenna element includes the top portion and an antenna pattern formed on the antenna board. A distance between the antenna base and a lower edge of the top portion is not less than 10 mm, and the lower edge of the top portion is bent downward. The top portion is configured such that an antenna capacitance of the antenna element becomes about 3 pF or more. A received signal from the antenna element is guided to an amplifier board through a connecting wire and amplified. An antenna case is fitted in the antenna base.||07-11-2013|
|20130076578||ANTENNA FOR VEHICLES - Disclosed is a type of antenna for vehicles that is protected by having a cap fitted-onto an antenna cover that covers an antenna element thereof, wherein coming-off of the cap is prevented from happening. The antenna for vehicles, which is comprised by having an antenna rod mounted onto an antenna base, is provided with: a conductive rod element that is formed within the antenna rod, and connected to the antenna base; a joint section that covers at least the side face of the rod element in the axis direction thereof, and that comprises an inner-side cylinder that is formed in the vicinity of an end section at the opposite side of the antenna base and further comprises a joint engaging section, and an outer-side cylinder that is formed at the outer side of the inner-side cylinder; and a rod cap that comprises a cop engaging section for engaging with the joint engaging section.||03-28-2013|
|20130033409||Radiation Antenna for Wireless Communication - A radiation antenna for wireless communication provides an advantage of being able to enhance gain and control directionality, while suppressing the height. The radiation antenna for wireless communication includes a line antenna element||02-07-2013|
|20130026331||MOUNTING BRACKET FOR ANTENNA - A plurality of projections of which leading edge is sharp is formed on an outer edge on a flat-plate shaped base plate of a mounting bracket. A washer formed with a plurality of protruding tips of which a leading edge is sharp at its upper rim is integrally formed at a substantially center portion of the base plate so as to protrude downward. A nut is rotatably mounted at a bottom portion of the washer. A frame of an antenna device has a shark-fin shape. A protruding screw protrudes from a bottom surface of an antenna base. When the nut of the mounting bracket is tightened to the protruding screw, a plurality of projection and the plurality of protruding tips sticks into a roof. This provides an antenna mounting bracket that does not wobble even if a shark-fin type vehicle antenna is mounted to a curved vehicle panel.||01-31-2013|
|20120206315||Vehicle Pole Antenna - A vehicle pole antenna fixed to an antenna support base includes: a rod||08-16-2012|
|20120081194||Vehicle-Mounted Noise Filter - Disclosed is a vehicle-mounted noise filter capable of suppressing electric field coupling between a pair of capacitors in the FM radio band, thereby allowing the intrinsic noise attenuation performance of a noise filter circuit to be exerted even in the FM radio band. The vehicle-mounted noise filter comprises a ground plate, a coil, a pair of capacitors, and a conductive shielding plate. The ground plate is grounded in a vehicle body. A lead wire is wound around the coil. The pair of capacitors are disposed such that the coil is interposed therebetween, and are electrically connected to the coil and the ground plate so as to form π-type filter circuit. The conductive shielding plate is grounded in the ground plate and is disposed between the pair of capacitors so as to shield the electric field coupling between the pair of capacitors.||04-05-2012|
