Abstract: A signal processing device may include a feeding apparatus having a first conductor configured to transmit a radio frequency signal; an insulating medium covering the first conductor; and a second conductor covering the insulating medium. The conductor may have first, second, and third portions. The third portion of the first conductor may be configured to be connected to the target apparatus to feed the radio frequency signal to the target apparatus and configured to form a capacitive impedance with the target apparatus, and the second portion of the first conductor may be configured to form an inductive impedance with the target apparatus. An absolute value of a sum of the capacitive impedance and the inductive impedance may be less than or equal to a preset impedance threshold.

Abstract: Base station antennas, and components for base station antennas, such as reflectors, feeder components, frames, and column components. A base station antenna may include a reflector; a first radiator located at the front side of the reflector; mutually parallel first and second ground plates extending backward from the reflector and basically perpendicular to the reflector; and a first conductor strip extending between the first and second ground plates and configured to feed power to the first radiator. The first conductor strip and the first and second ground plates may be configured as a first stripline transmission line. The reflector and the first and second ground plates may be configured as one piece so that the reflector is grounded via the first and second ground plates without soldering.

Abstract: A feed network includes an adjustable electromechanical phase shifter that comprises a main printed circuit board and a phase shifting unit. The adjustable electromechanical phase shifter is configured to shift the phase of an RF signal that is input to the feed network and provide the phase shifted RF signal to at least one radiating element that is positioned on a first side of a reflector of an antenna, where the phase shifting unit is formed on the surface of a first side of the main printed circuit board, and the first side of the main printed circuit board is a side that is closer to the at least one radiating element, and the main printed circuit board is positioned on the first side of the reflector.

Abstract: 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.
