摘要： This application provides an antenna system and a base station antenna feeder system. The antenna system includes a first antenna and a second antenna. The first antenna includes a first radiating element array and a first phase shifter, and the first phase shifter is electrically connected to the first radiating element array. The second antenna includes a second radiating element array and a second phase shifter, and the second phase shifter is electrically connected to the second radiating element array. The first phase shifter is disposed at an edge of the first antenna, and the first phase shifter is configured to be detachably connected to the second antenna. In the antenna system in this solution, the first antenna and the second antenna can be detachably connected, so that an antenna configuration can be upgraded without replacing an original antenna and with low costs and a convenient operation.

摘要： This application provides an antenna and a base station antenna feeder system. The antenna includes a first phase shifter, where the first phase shifter includes a cavity and a phase-shift circuit. The phase-shift circuit is disposed in the cavity. The cavity is connected to a mounting structure, and the mounting structure is configured to connect to a pole. In this solution, the cavity can support the entire antenna using the cavity of the first phase shifter as a frame of the antenna, and by mounting the cavity of the first phase shifter on the pole with the mounting structure. In this solution, the cavity of the first phase shifter is used as a force-bearing framework of the antenna to bear a weight of the antenna, to help improve stability of the mounting structure of the antenna, so that the antenna is not prone to damage, a service life of the antenna is prolonged, and performance of the antenna of a base station is ensured.

摘要： A transmission module (30) includes n oscillator modules (50) and a phase command signal generator (40). Each of the oscillator modules (50) includes a voltage controlled oscillator (60) and an amplification circuit (70). The voltage controlled oscillators (60) output transmission high-frequency signals having the same frequency and synchronized among the n oscillator modules (50) by synchronous control based on a common reference signal (Sr). The amplification circuits (70) each perform power amplification for the transmission high-frequency signal from a corresponding one of the voltage controlled oscillators (60) and output the resultant signal. Phases of the transmission high-frequency signals synchronized among the n oscillator modules (50) and output from the voltage controlled oscillators (60) are separately controlled according to respective n phase command signals (ϕ1* to ϕn*) from the phase command signal generator (40).

摘要： Embodiments of the present invention provide a phased array system and a beam scanning method. The phased array system includes at least two traveling wave antennas (21) arranged in parallel, and each traveling wave antenna (21) includes at least two antenna units (22) sequentially connected; and a first end (23) of each traveling wave antenna (21) connects to a corresponding first radio frequency channel (20), the first end (23) of each traveling wave antenna (21) connects to a signal processing module (24) of the phased array system by using the corresponding first radio frequency channel (20), and a phase and/or an amplitude of a signal inputted by the signal processing module (24) from the first end (23) into the traveling wave antenna (21) may be adjusted by adjusting a configuration of the first radio frequency channel (20). According to the phased array system and the beam scanning method, based on implementation of spatial beam scanning, a requirement for a quantity of radio frequency channels is reduced, and therefore complexity and costs of the phased array system are reduced.

摘要： A microwave component of cavity type includes an integral cavity and a microwave network circuit disposed in the cavity. The cavity has multiple enclosing walls and a chamber defined by said multiple enclosing walls. The chamber is intended for accommodating the microwave network circuit therein. A wiring slot is defined in at least one of the enclosing walls, and at least one first through hole extended through the chamber is provided on each wiring slot. The microwave component of cavity type features small size, simple structure, and wide application. Furthermore, cost may be reduced, batch production may be achieved, use of fasteners such as screws is avoided, and the passive inter-modulation products caused by fasteners are eliminated, as the microwave component is secured without any screws.
