Abstract: A multi-antenna system includes a conductive plane with four adjacent sides, a main antenna unit disposed on any one of the four sides, a first secondary antenna unit disposed on any one of the four side, a second secondary antenna unit disposed on any one of the four sides of the conductive plane except the side on which the main antenna unit is disposed, a switching circuit disposed on the conductive plane and is selectively electrically connected to the first secondary antenna unit or the second secondary antenna unit and a wireless communications module disposed on the conductive plane and electrically connected to the switching circuit and the main antenna unit. The first secondary antenna unit is spaced apart from the main antenna unit by a spacing, where the spacing is greater than 0.5 times a wavelength distance of a low-frequency operating frequency of the multi-antenna system.

Abstract: Exemplary embodiments are disclosed of antenna assemblies configured for reception of television signals, such as high definition television (HDTV) signals. In an exemplary embodiment, an antenna assembly generally includes a VHF antenna element and a UHF antenna element. The VHF antenna element and the UHF antenna element may be parasitically coupled without a direct ohmic connection between the VHF antenna element and the UHF antenna element. The antenna assembly may be configured to be operable for receiving VHF and UHF high definition television signals without using a diplexer and a VHF balun.

Abstract: A semiconductor device package includes a substrate, a first antenna pattern and a second antenna pattern. The substrate has a first surface and a second surface opposite to the first surface. The first antenna pattern is disposed over the first surface of the substrate. The first antenna pattern has a first bandwidth. The second antenna pattern is disposed over the first antenna pattern. The second antenna pattern has a second bandwidth different from the first bandwidth. The first antenna pattern and the second antenna pattern are at least partially overlapping in a direction perpendicular to the first surface of the substrate.

Abstract: An antenna device includes a ground electrode, a feed element, and a parasitic element. The ground electrode has a substantially non-square rectangular plane shape that includes a first side extending in a first direction and a second side extending in a second direction orthogonal to the first direction. The feed element has a substantially rectangular plane shape and is formed in such a way that each side of the feed element becomes parallel to the first direction or the second direction. The parasitic element is formed in such a manner as to face a side of the feed element parallel to the first side. The feed element is configured to radiate a first polarized wave that excites in the first direction and a second polarized wave that excites in the second direction. The length of the first side is longer than the length of the second side.

Abstract: A radiating element comprises a radiator, a feed stalk and a parasitic element. The radiator is fed by the feed stalk, and the parasitic element includes an electrically conductive structure that includes a meandered electrically conductive path. A coupling capacitor is formed between the electrically conductive structure and the radiator, and a center frequency of an operating frequency band of the radiator is higher than a center frequency of a first operating frequency band of the parasitic element.

Abstract: A first ground conductor is disposed in or on a main substrate. In or on an antenna module, a first antenna and a second ground conductor operating as a ground electrode of the first antenna are disposed. A coaxial cable including a core wire and an outer conductor feeds power to the first antenna. The outer conductor is electrically connected to the first ground conductor at a first position, and is connected to the second ground conductor at a second position. A second antenna including a feed element and a parasitic element operates at a lower frequency than the operating frequency of the first antenna. The second ground conductor and a part of the outer conductor from the first position to the second position also serve as the parasitic element of the second antenna.

Abstract: An antenna structure includes a housing, a first feed source, a ground portion, a radiator, and a second feed source. The housing includes a front frame, a backboard, and a side frame. The side frame defines a slot. The front frame defines a first gap, a second gap, and a groove. A radiating portion and a coupling portion are divided from the housing by the slot, the first gap, the second gap, and the groove. The first feed source is electrically connected to the radiating portion. One end of the ground portion is electrically connected to the radiating portion and another end of the ground portion is grounded. The radiator is coupled with and apart from the coupling portion. The second feed source is electrically connected to the radiator and a current from the second feed source is coupled to the coupling portion through the radiator.

The conductor patterns include first, second, third, and fourth conductor patterns, and the interlayer connection conductors include first and second interlayer connection conductors. The first conductor pattern, the second conductor pattern, and the first interlayer connection conductor define a first coil, and the third conductor pattern, the fourth conductor pattern, and the second interlayer connection conductor define a second coil. The first coil and the second coil are disposed in a region of less than about ⅓ of a stacking height of a multi-layer body including the insulating layers.
