A phase shifter according to at least one embodiment of the present disclosure has a housing provided on both surfaces with respective shifting units. Each shifting unit is composed of a fixed board and a moving board. Movement of the moving board causes a phase-shifted signal to be simultaneously transferred from both surfaces of the housing to output ports. This allows more effective use of the space of the phase shifter and therearound.

A multiband antenna array includes a radiating element array having first and second rows of MIMO radiating elements. The two rows of MIMO radiating elements include a plurality of dual-polarised radiating elements. The radiating element array includes a dual-polarised low-band radiating element. A reflector array is provided, from which a) the dual-polarised radiating elements of the first and second rows of MIMO radiating elements and b) the dual-polarised low-band radiating element are spaced. The dual-polarised low-band radiating element includes at least four directive radiating element devices, which are each offset relative to one another by at least approximately 90 and delimit an accommodation space. In the accommodation space there are at least one or at least two dual-polarised radiating elements from the first row of MIMO radiating elements and at least one or at least two dual-polarised radiating elements from the second row of MIMO radiating elements.

An antenna module including a first antenna and a second antenna close to the first antenna. The second antenna includes an isolation circuit and a second tuning switch controlling an access state of the isolation circuit. The second tuning switch includes two modes. When the second tuning switch is in a first mode, the isolation circuit accesses to a feeding network of the second antenna. When the second tuning switch is in a second mode, the isolation circuit does not access to the feeding network of the second antenna. Isolation of the first antenna and the second antenna in a preset band in the first mode is superior to that in the second mode.

Disclosed is a shark fin antenna for a vehicle. The shark fin antenna has a pad and a base disposed on the pad to provide a space for a printed circuit board and a plurality of antenna components. The shark fin antenna includes a holder having a groove therein for exposing at least a portion of an upper surface of a printed circuit board, a first antenna unit supported by the holder and having an antenna pattern formed on a surface thereof to receive an AM/FM frequency band signal, a first auxiliary unit covering at least a portion of an upper surface of the first antenna unit, and a spring mounted in the groove to elastically support the first auxiliary unit and the first antenna unit in a vertical direction of the upper surface of the printed circuit board.

A radio frequency antenna array uses multiple lenses, and mechanically movable elements, to provide ground-based and sky-based coverage for multiple object communication and tracking. The antenna array includes at least two spherical lenses, where each spherical lens has at least two associated RF elements. A third lens is added, along with at least two additional RF elements to narrow and track the overlapped beams from the first and second lenses. Each lens also includes a sub-controller configured to adjust a phase of the signals produced by the RF elements. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically configure the phase shifter to modify a phase of the output signals from the elements based on the relative positions between the RF elements. The overlapped beams track independent targets, such as satellites, across an area.
