技术领域Technical field
本申请涉及移动通讯基站天线技术领域，特别涉及一种介质移相器。This application relates to the technical field of mobile communication base station antennas, and in particular to a dielectric phase shifter.
背景技术Background technique
在移动通信覆盖中，电调天线相较于常规的机械下倾天线而言能更为灵活的适应于现代复杂的场景，逐步成为下倾天线的首选。随着5G通讯技术的逐步(快速)发展和应用环境的复杂化，固定倾角的5G天线已经满足不了未来的发展需求。因此电调技术也顺势而为的应用于5G天线中，而移相器为电调技术的关键部件，其大小和性能将直接影响5G天线的大小和指标。In mobile communication coverage, electronically adjustable antennas are more flexible to adapt to modern complex scenarios than conventional mechanical downtilt antennas, and gradually become the first choice for downtilt antennas. With the gradual (rapid) development of 5G communication technology and the complication of the application environment, fixed-tilt 5G antennas can no longer meet future development needs. Therefore, the ESC technology is also used in 5G antennas. The phase shifter is a key component of the ESC technology, and its size and performance will directly affect the size and indicators of the 5G antenna.
介质移相器主要是通过传动带动带线上覆盖的介质板滑动，通过使覆盖介质的带状线的长度变化，从而引起相位的改变。要想移相器的移相量大，传输线上覆盖的介质变化的长度就要大。The medium phase shifter mainly drives the medium plate covered by the belt line to slide through the transmission, and causes the phase change by changing the length of the belt line covering the medium. If the phase shift of the phase shifter is to be large, the length of the change of the medium covered on the transmission line must be large.
但是加长传输线长度变化范围又会带来一系列诸如移相器的电机尺寸、幅度波动、驻波比、***损耗等电气性能稳定性的技术难题。现有介质移相器的缺点是移相量小、尺寸过大，且调节方式单一。However, extending the transmission line length variation range will bring a series of technical problems such as the electrical performance stability of the phase shifter's motor size, amplitude fluctuation, standing wave ratio, and insertion loss. The disadvantages of the existing medium phase shifters are that the phase shift is small, the size is too large, and the adjustment method is single.
