摘要： Disclosed is an electronic device including an antenna module including a first antenna element and a second antenna element, and a processor operatively connected to the antenna module. The processor may be configured to transmit a first signal through the first antenna element, to receive a second signal including a signal obtained as the first signal is reflected by a target object, through the second antenna element, to calculate a distance from the antenna module to the target object based on a phase of the second signal, and to reduce a power level of the antenna module when the distance to the target object is smaller than a reference distance. In addition, various embodiments as understood from the specification are also possible.

摘要： An electronic device comprises a first radiator coupled to a second radiator. One end of a second branch of the second radiator is connected between a head end and a tail end of a first branch of the second radiator. The other end of the second branch is connected between a head end and a tail end of a third branch of the second radiator. A projection of a reference face of the first branch on the first radiator is a first projection. The first projection partly overlaps the first radiator, or a distance between the first projection and the first radiator is within a range of 0 to 3 millimeters. A ratio of a first center distance between an end face of the third branch and the reference face, and a second center distance between the other end face of the third branch and the reference face is within a range of 0.5 to 2.

摘要： Disclosed is a frequency-division duplexing (FDD) type antenna device for implementing spatial-polarization separation of beams using a quad-polarized antenna module array.
There is provided an antenna device including first radiating elements, second radiating elements, third radiating elements, and fourth radiating elements, a filter unit including first, second, third, and fourth filters that filter signals of first, second, third, and fourth signal paths, respectively, and a phase setting module configured to set phases of the filtered signals so that a first beam and a second beam radiated through the first and second radiating elements and the third and fourth radiating elements, respectively, are separated in space, wherein the first beam and the second beam have different polarization directions.-

摘要： An antenna device includes a first antenna unit, a second antenna unit and a third antenna unit. An angle between the second antenna unit and the first antenna unit is substantially equal to 90 degrees. An angle between the third antenna unit and the first antenna unit is substantially equal to 90 degrees. The first antenna unit and the second antenna unit are configured to generate a signal having a first polarization when the third antenna unit is turned off. The third antenna unit and the second antenna unit are configured to generate a signal having a second polarization different from the first polarization when the third antenna unit is turned off. A method of generating polarized signals is also disclosed herein.

摘要： An apparatus and method for wavelength conversion of a signal, for example, a dual-polarization signal, is disclosed. The apparatus implements a single-loop counter-propagating wavelength conversion scheme which provides both up-conversion and down-conversion of the signal within the same loop. Nonlinear wavelength conversion devices in the loop provide both up-conversion and down-conversion of the polarization components of the signal within the loop depending on whether the polarization component travels through the nonlinear conversion device in a clockwise or a counter-clockwise direction. The wavelength-converted signal is available to be extracted from the wavelength-conversion loop. An all-optical wavelength-division multiplexing transponder based on the wavelength-conversion scheme is also disclosed.

摘要： An antenna module includes a power supply element and a ground electrode (GND) arranged so as to face the power supply element. In a plan view of the antenna module from a normal direction, when a minimum distance along the first direction between a center of the power supply element and an end portion of the ground electrode (GND) is defined as a first distance, a minimum distance between the center of the power supply element and an end portion of the ground electrode (GND) is defined as a second distance, and a distance between the end portion of the ground electrode (GND) and an end portion of the power supply element in the second distance is defined as a third distance, the first distance is longer than the second distance, and the third distance is shorter than ½ of a size of the power supply element.

摘要： An electronic device may be provided with wireless circuitry and a housing with upper and lower ends. The lower end may include first and second open slot antennas that are directly fed by respective feeds and that radiate in a cellular ultra-high band. The lower end may also include first and second inverted-F antennas. The upper end may include third and fourth inverted-F antennas. The first inverted-F antenna may have a first feed that conveys currents below 2700 MHz and a second feed that conveys antenna currents in the cellular ultra-high band, a wireless local area network band, and/or ultra-wideband frequency bands. If desired, the upper end may include a third open slot antenna that is directly fed by a corresponding antenna feed and that radiates in the cellular ultra-high band and/or in the ultra-wideband frequency bands.

摘要： A communication device includes a ground element, an antenna structure, a first reflector, a second reflector, a first tuning element, and a switch element. The first reflector is disposed adjacent to the antenna structure. The second reflector is disposed adjacent to the antenna structure. The second reflector is separate from the first reflector. The switch element is coupled to the first tuning element. When the switch element is enabled, the switch element couples the first tuning element to the first reflector or the second reflector. When the switch element is disabled, the first tuning element is separate from the first reflector and the second reflector.

During operation, the electronic device may configure switching elements to: select the first pair of antennas and electrically couple the second pair of antennas to ground; or select the second pair of antennas and electrically couple the first pair of antennas to ground. Then, the electronic device may communicate a packet or a frame with a second electronic device via the selected first pair of antennas or the second pair of antennas.
