20090179808 | Antenna Having Wide Impedance Bandwidths Both at Low and High Frequencies - An antenna includes a base element, grounding and feeding points, and first and second radiating elements. Each of the grounding and feeding points is provided on the base element. The first radiating element is operable in a first frequency band, and extends from the base element. The second radiating element is operable in a second frequency band lower than the first frequency band, extends from the base element, and is formed with a slot. | 07-16-2009 |
20090195478 | Low-Profile Antenna - An antenna includes a dielectric substrate, feeding and grounding elements, a base element, a radiating element, and an interconnecting element. The feeding and grounding elements are formed on the dielectric substrate. The base element is mounted on the dielectric substrate such that the base element is in electrical contact with the feeding and grounding elements. The radiating element is spaced apart from the dielectric substrate. The interconnecting element interconnects the base element and the radiating element. | 08-06-2009 |
20090237307 | Ultra-Wideband Antenna - An antenna includes first and second radiating elements and a conductive arm. The second radiating element has opposite feeding and grounding end portions, each of which is coupled to a respective one of feeding and grounding end portions of the first radiating element. The conductive arm is coupled to the feeding end portion of the second radiating element. | 09-24-2009 |
20090237308 | Planar Antenna - An antenna includes first and second radiating elements. The first radiating element is operable in a first frequency range. The second radiating element cooperates with the first radiating element to define a slot therebetween in such a manner that the second radiating element is coupled electromagnetically to the first radiating element. The construction as such permits operation of the second radiating element in a second frequency range different from the first frequency range, and a third frequency range different from the first and second frequency ranges. | 09-24-2009 |
20090243947 | Antenna With First and Second Loop Radiating Elements - An antenna includes a dielectric substrate, first and second feeding points, first and second grounding points, first and second loop radiating elements, and a grounding element. The first and second feeding points and the first and second grounding points are formed on the dielectric substrate. The first and second radiating elements are spaced apart from each other and have a shape and a size that are identical. Each of the first and second loop radiating elements is operable in a frequency range, and has a feeding end coupled to a respective one of the first and second feeding points, and a grounding end coupled to a respective one of the first and second grounding points. The grounding element is formed on the dielectric substrate and is disposed between the first and second loop radiating elements. | 10-01-2009 |
20100045534 | Antenna - An antenna includes: a grounding element extending along a first plane; a radiating element having a first side and extending along a second plane substantially parallel to the first plane, the radiating element being aligned with the grounding element in a normal direction transverse to the first and second planes; a bridging element interconnecting the grounding and radiating elements; and a feeding element extending and tapered from the first side of the radiating element toward the grounding element. | 02-25-2010 |
20100149044 | SMALL-SIZED ANTENNA - An antenna includes first and second dielectric substrates, a grounding element, and a radiating unit. The first dielectric substrate extends on a horizontal plane. The grounding element is formed on the first dielectric substrate. The second dielectric substrate extends on a vertical plane transverse to the horizontal plane and is disposed on the first dielectric substrate. The radiating unit is formed on the second dielectric substrate, and is provided with a feeding point, and a grounding point coupled to the grounding element. | 06-17-2010 |
20100164832 | ANTENNA DEVICE - An antenna device includes a grounding element and an antenna. The antenna includes a feeding element, first and second radiating elements, and a parasitic element. The first radiating element is coupled to the grounding element. The second radiating element is coupled to the feeding element, is disposed proximate to the first radiating element, and cooperates with the grounding element and the first radiating element to define an area thereamong. The parasitic element is disposed in the area and extends from the grounding element. | 07-01-2010 |
