摘要： A radiating element may have a dipole arm that may include a first conductive circuit loop and a second conductive circuit loop. The first conductive circuit loop may include at least one narrow conductive segment and at least one wide conductive segment, and the narrow conductive segment may present high impedance characteristics in at least one frequency band outside the operating frequency band of the radiating element to suppress at least partially the current in the at least one frequency band. A base station antenna may include a feed board and the radiating element mounted on the feed board.

摘要： Described are electronic devices, and specifically provides a multi-frequency slot antenna, a terminal device and an antenna resonance frequency adjustment method. The antenna is applied to a terminal device, and the terminal device includes a metal casing. According to an example, the antenna includes a slot provided in the metal casing, the slot having a first end and a second end opposite to each other in a length direction; a feed terminal across inside of the slot and located between the first end and the second end; and a capacitor provided in the slot, two electrodes of the capacitor being respectively connected with two sides of the slot in a width direction. Furthermore, in the length direction, the capacitor is located at a position where voltages are not zero at original values of multiple orders of resonance frequencies of the antenna when the capacitor is not provided in the slot. In this way, an operating frequency of the antenna includes multiple orders of resonance frequencies.

摘要： A dual-band antenna device allowed to perform communication at a first frequency in a predetermined frequency band and at a second frequency in a frequency band higher than the predetermined frequency band includes: a ground conductor; a folded antenna conductor including a first linear part and a second linear part that are caused to face each other at a distance by folding; an LC resonant circuit that is included in the folded antenna conductor, that lets the first frequency pass, and that lets the second frequency attenuate; and a feeding point between the ground conductor and the folded antenna conductor. A narrow gap part is provided between the first linear part and the second linear part of the folded antenna conductor, the narrow gap part measuring a distance shorter than a distance measured in a different portion between the first linear part and the second linear part.

摘要： An antenna assembly and method are disclosed. The antenna assembly comprises: a printed circuit board assembly having a radiating element layer and a choke structure, the choke structure having a central conductor and a shielding structure, wherein the central conductor comprises at least a portion of the radiating element layer. By providing a printed circuit board assembly having a radiating element layer and a choke structure which utilises a portion of the radiating element layer, the manufacture of the radiating elements is simplified.

摘要： An electronic device may include a housing and four antennas at respective corners of the housing. Cellular telephone transceiver circuitry may concurrently convey signals at one or more of the same frequencies over one or more of the four antennas using a multiple-input multiple-output (MIMO) scheme. In order to isolate adjacent antennas, dielectric-filled openings may be formed in conductive walls of the housing to divide the walls into segments that are used to form resonating element arms for the antennas. If desired, first and second antennas may include resonating element arms formed from a wall without any gaps. The first and second antennas may include adjacent return paths. A magnetic field associated with currents for the first antenna may cancel out with a magnetic field associated with currents for the second antenna at the adjacent return paths, thereby serving to electromagnetically isolate the first and second antennas.

摘要： Base station antennas are provided herein. A base station antenna includes a plurality of vertical columns of low-band radiating elements configured to transmit RF signals in a first frequency band. The base station antenna also includes a plurality of vertical columns of high-band radiating elements configured to transmit RF signals in a second frequency band that is higher than the first frequency band. The vertical columns of high-band radiating elements extend in parallel with the vertical columns of low-band radiating elements in a vertical direction.
