Title:
PHASE SWITCHER AND ELECTRIC TILT ANTENNA
Document Type and Number:
WIPO Patent Application WO/2020/024893
Kind Code:
A1
Abstract:
The present application provides a phase shifter and an electric tilt antenna comprising same. The phase shifter comprises a cavity, and metal stripline, a slide medium, and fixing members. The fixing members fix the metal stripline in the cavity, so that a transmission portion of the metal stripline is suspended in the cavity. The metal stripline does not need to be disposed on a substrate, such that the loss of signal energy caused by the substrate is reduced, thereby reducing the heat generated due to signal energy loss and reducing the requirement on the heat dissipation and heat resistance of the internal structure members of the phase shifter.
