摘要： An apparatus and associated method are provided involving a housing having a periphery configured to operate as a second antenna, a third antenna, and a fourth antenna. The periphery includes a top wall having a first slot formed therein, a first side wall having a second slot formed therein, and a second side wall having a third slot formed therein. The top wall is arranged between the first side wall and the second side wall, and a top portion of the periphery is defined between the second slot and the third slot. The top portion is divided into a first top side portion and a second top side portion via the first slot. Further, the first top side portion operates as the second antenna, and the second top side portion operates as both the third antenna and the fourth antenna.

摘要： By performing continuous matching in an entire frequency band from 600 MHz to 6 GHz by one antenna device, communication with a plurality of types of communication devices having different used frequency bands becomes possible without switching the antenna device.
In the antenna device, a first insulating plate 40, a capacitive coupling portion 45a of a tuning plate 45, a radio wave absorber 50, a grounding portion 45b of the tuning plate 45 folded back to the back side of the radio wave absorber 50, and a tuning coated plate 55 provided with a metallic plated film formed on the surface thereof are sequentially stacked below an antenna element 30 having a shape obtained by removing an arched portion from a copper circular plate.
Power is supplied from a center conductor 64 of a semi-rigid signal input member 61 to a power feeding unit 33 provided in a part of a circular outer edge 32 of the antenna element 30. An external conductor 62 of the signal input member 61 is held between conductive cushions 80a and 80b that are elastically deformable. A grounding plate 85 is conductive with the external conductor 62, to ground the grounding portion 45b and the tuning coated plate 55.

摘要： The present disclosure relates to an antenna structure and an electronic device. The antenna structure includes: a metal frame body; a first antenna branch coupled to one side edge of the metal frame body; a second antenna branch coupled to the other side edge of the metal frame body; an antenna gap defined by the first antenna branch and the second antenna branch after the first antenna branch and the second antenna branch both extend towards a middle portion of the metal frame body, an extension length of the first antenna branch being greater than an extension length of the second antenna branch; and a feed point with one end coupled to a ground point and the other end coupled to the first antenna branch.

摘要： A direction-finding antenna (100) includes at least a first set of radiating elements (102A-D) configured to radiate at least a first wavelength (λ 1 ) and a second set of radiating elements (104A-D) configured to radiate at a second wavelength (λ 2 ) that is shorter than the first wavelength (λ 1 ). The first set of radiating elements defines a first circle having a first radius. The second set of radiating elements defines a second circle having a second radius that is smaller than the first radius of the first circle. The direction-finding antenna further includes a transmission line-based multiplexer (110) configured to selectively couple the first set of radiating elements or the second set of radiating elements to a radio frequency (RF) feed line (108), or a plurality of switches (112) configured to selectively couple selected radiating elements of the first set of radiating elements or the second set of radiating elements to the RF feed line.
