摘要： The present invention provides a balanced dipole unit and a broadband omnidirectional collinear array antenna formed by the balanced dipole unit. Balanced dipole unit circuits in the balanced dipole unit are symmetrically distributed on two sides of a circuit carrier, and a feeder and a ground wire in the balanced dipole unit are also symmetrically distributed, so that the balanced dipole unit has a completely symmetrical structure. A principle of the symmetrical structure is the same as a differential design principle and a self-balancing principle in the circuit design, thereby reducing current coupling between the balanced dipole units and eliminating the need of using an additional choke circuit when a broadband omnidirectional collinear array antenna is formed by the balanced dipole unit.

摘要： An antenna structure includes a h-shaped radiator and a first radiator. The h-shaped radiator has a first segment, a second segment opposite to the first segment, a first end and a second end which are located at the first segment, a third end located at the second segment, a short-circuit point at the first segment, and a feeding point at the second segment, in which the first segment is longer than the second segment. The first radiator is connected to the second segment.

摘要： Antenna structures and methods of operating the same of a dual-band inverted-F antenna of an electronic device are described. One device includes a single RF feed line coupled to a dual-band inverted-F antenna. The dual-band inverted-F antenna includes a RF feed coupled to the single RF feed line; a ground element; a first arm; a second arm; and a third arm coupled to the ground element. The RF feed is located at a point that is closer to the third arm than a first opening between a distal end of the first arm and the ground element. The second arm is located on an opposite side of the first arm than the ground element, forming a second opening between the second arm and the ground element and a third opening between the second arm and the first arm.

摘要： An antenna assembly can be configured for RF communications. The antenna assembly can include a ground plane disposed on a substrate. The antenna assembly can include a patch antenna structure spaced apart from the ground plane. The antenna assembly can include one or more grounded posts coupled to and extending from the substrate. The one or more grounded posts can be arranged along at least a portion of a periphery of the patch antenna structure. The patch antenna structure can emit a radiation pattern based at least in part on a transmit signal. The radiation pattern can induce a resultant field in the one or more grounded posts to adjust a characteristic of the radiation pattern.

摘要： An antenna includes a first folded dipole, and a second folded dipole connected in parallel to the first folded dipole. The antenna further includes a conductor that extends across a first gap in the first folded dipole and a second gap in the second folded dipole to connect to a first central section of the first folded dipole and to a second central section of the second folded dipole.

摘要： Antenna systems, devices, and methods for providing both end-fire mm-wave high-frequency signals and low-frequency RF signals from a collocated antenna array in which at least one high-frequency antenna element and a low-frequency antenna element are spaced apart from one another. Grating strips are positioned between the high-frequency antenna elements and the low-frequency antenna element, the grating strips being spaced apart from one another by a defined spacing. The grating strips are configured such that a signal wave from the high-frequency antenna element propagates through the low-frequency antenna element.

摘要： A dipole antenna includes a reflector, a radiating element, and a feed element. The radiating element includes first and second dipoles above a surface of the reflector. The first and second dipoles respectively include arm segments and are arranged in a crossed dipole arrangement. The feed element includes first and second conductive transmission lines that are electrically isolated from one another and are capacitively coupled to the arm segments of the first and second dipoles, respectively. The arm segments of the first and second dipoles are between the feed element and the surface of the reflector.

摘要： Disclosed are improved antenna structures, systems, and methods of manufacturing. In an embodiment, low-cost internal 2G/5G antennas have flat metal dipole construction, which can include a stiffener. External embodiments include quad dipole antenna structures, with broadside or corner arrays. Isolated multi-band center or end-fed dipole antennas can include single-sided PCB or metal-only structures, for operation with at least two distinct frequencies, and can provide RF isolation, such as with an RF trap or a Balun system. Embodiments of non-DC path or pass-through dual band antennas feature trap structures, along with discrete or distributed matching, and can provide a DC feed path for LEDs. Low profile and flat vertically polarized omni-directional antennas, such as for operation at 915 MHz, include an open slot driven cavity. Stacked 2G/5G antenna structures provide axial symmetry between quadrants. Improved construction methods and antenna structures include enhanced thin metal components and low cost, crimp-only construction methods.
