摘要： An electronic device may be provided with peripheral conductive housing structures, a first antenna, and a second antenna. A gap may divide the housing structures into a first segment forming an arm of the first antenna and a second segment forming an arm of the second antenna. A first feed terminal may be coupled to the first segment and a second feed terminal may be coupled to the second segment. Switchable components may be coupled in parallel between the first and second feed terminals across the gap. The switchable components may be adjusted to tune the frequency response of the first and/or second antenna. The switchable components may have a first state in which only the first feed terminal feeds the first antenna and may have a second state in which both the first and second feed terminals feed the first antenna.

摘要： An antenna module includes a dielectric substrate, radiating circuits disposed on the dielectric substrate, a ground electrode, and a dielectric layer. In a plan view in a direction of a normal line of the dielectric substrate, the radiating circuit is disposed adjacent to the radiating circuit. The ground electrode is disposed to face the radiating circuit and the radiating circuit. The dielectric layer is disposed to cover the radiating circuit. The radiating circuit is capable of emitting an electric wave in a frequency band higher than that for the radiating circuit. A dielectric constant of the dielectric layer is higher than a dielectric constant of the dielectric substrate. A distance between the radiating circuit and the ground electrode is shorter than a distance between the radiating circuit and the ground electrode.

摘要： An apparatus is disclosed herein for a cylindrically fed antenna and method for using the same. In one embodiment, the antenna comprises: an antenna feed to input a cylindrical feed wave; a first layer coupled to the antenna feed and into which the feed wave propagates outwardly and concentrically from the feed; a second layer coupled to the first layer to cause the feed wave to be reflected at edges of the antenna and propagate inwardly through the second layer from the edges of the antenna; and a radio-frequency (RF) array coupled to the second layer, wherein the feed wave interacts with the RF array to generate a beam.

摘要： Devices and methods for implementing MIMO in metal ring structures using tunable electrically small antennas. In some embodiments, the metal ring structure includes a mobile device including electrically small antennas arranged on it, tunable band-stop circuits, wherein each of the electrically small antennas has a largest dimension that is substantially equal to or less than one-tenth of a length of a wavelength corresponding to a frequency within a communications operating frequency band. In some embodiments, the tunable electrically small antennas utilize parts of the metal ring structure of the mobile device as antenna radiators. The TESA are tunable for low-band frequencies between about 600 MHz-960 MHz. Additionally, the TESA have a wide bandwidth in high-band between about 1700 MHz-2700 MHz. In order to separate the TESA radiators from the rest of the metal ring structure, the radiators are connected by insulating material.
