Abstract:
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.
Abstract:
An antenna device includes a dielectric substrate, first and second antennas, and a parasitic coupler. The first antenna is formed on the dielectric substrate, and includes first and second radiating elements that extend in opposite directions. The parasitic coupler is formed on the dielectric substrate and is electromagnetically coupled to the first radiating element. The second antenna is formed on the dielectric substrate and is disposed proximate to the second radiating element.
Abstract:
An antenna unit includes left and right antennas that are spaced apart from each other and that are operable within a first frequency bandwidth, and a parasitic coupler that is spaced apart from and disposed between the left and right antennas, and that is electromagnetically coupled to the left and right antennas so as to be operable within a second frequency bandwidth.
Abstract:
An antenna includes loop and single-pole antenna members, and an inductor. The single-pole antenna member is spaced apart from the loop antenna member. The inductor has a first inductor terminal coupled to the loop antenna member, and a second inductor terminal coupled to the single pole antenna member. A desired resonance frequency of the antenna can be achieved by simply adjusting the inductance of the inductor.
Abstract:
A planar antenna includes a high frequency radiating element, a meandering low frequency radiating element, and an interconnecting element. The low frequency radiating element has an operating bandwidth which is lower than that of the high frequency radiating element. The interconnecting element interconnects the high frequency radiating element and the low frequency radiating element. A feeding point is provided on the high frequency radiating element and is distal from the interconnecting element. A grounding point is provided on either the interconnecting element, or the high frequency radiating element proximate to the interconnecting element.
Abstract:
An electronic device includes a casing, an antenna, a signal attenuating member, and a signal reflecting member. The antenna is disposed in the casing for radiating an electromagnetic signal. The signal attenuating member is mounted on the casing. The signal reflecting member is disposed between the antenna and the signal attenuating member, is free of physical contact with the antenna, and reflects a portion of the electromagnetic signal, which is radiated by the antenna toward the signal attenuating member, away from the signal attenuating member.
Abstract:
A dual-band antenna includes first and second connecting sections coupled to a ground unit, and first, second, and third radiator sections. The first connecting section extends in a direction from the ground unit toward an inner wall face of a housing of an electronic device. The first radiator section is connected to the first connecting section and is disposed to extend along the inner wall face. A feed-in section extends between the second connecting section and the inner wall face, and has a portion extending parallel to the first radiator section. The second radiator section is connected to the feed-in section and is disposed to extend along the inner wall face. The third radiator section is connected to the second radiator section, extends between the second radiator section and the feed-in section, and has a portion extending parallel to the second radiator section.
Abstract:
A multi-band antenna module is disposed in a housing of an electronic device. The housing has a grounding plane disposed therein and includes a metal frame part having two ends electrically connected to opposite side edges of the grounding plane. The multi-band antenna module includes a conductor, a substrate, a grounding section, and a first radiator section. The conductor is to be coupled across the metal frame part and the grounding plane so as to cooperate with the grounding plane and a portion of the metal frame part to form a closed loop thereamong, in which the substrate is disposed. The first radiator section and the grounding section are disposed on the substrate, with the grounding section to be coupled electrically to the grounding plane. A portion of the first radiator section is disposed to cooperate with the closed loop to resonate in a first frequency band. Another portion of the first radiator section is disposed to cooperate with the grounding section to resonate in a second frequency band.
Abstract:
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.
Abstract:
An antenna, which is operable in a digital video broadcasting for handhelds (DVB-H) frequency range, includes first and second monopole radiating elements and a feeding element. The first and second monopole radiating elements are symmetrical about an axis of symmetry and have a meandering shape. The feeding element interconnects the first and second monopole radiating elements.
