The invention relates to an electric tuning device and an antenna system. The electric tuning device comprises a metal shielding shell, a motor and a mounting plate. One end face of the metal shielding shell is provided with an output shaft hole. The motor and the mounting plate are both arranged in the metal shielding shell, and an output rotating shaft of the motor extends out of the metal shielding shell through the output shaft hole. The mounting plate is fixedly arranged in the metal shielding shell through a first mounting piece. The motor is fixedly arranged on the mounting plate through a second mounting piece. The first mounting piece and the second mounting piece are both arranged in the metal shielding shell. An external mounting piece does not appear on the end face where the output shaft hole of the metal shielding shell is located, furthermore, the end face where the output shaft hole of the metal shielding shell is located does not have a mounting hole matched with the mounting piece, namely, a contact gap does not exist, and the end face where the output shaft hole of the metal shielding shell is located is a smooth surface, so that clutter signals do not appear inmain signals of the antenna system, and a better intermodulation index can be realized.
Description
technical field [0001] The invention relates to the technical field of communication antennas, in particular to an electric adjustment device and an antenna system. Background technique [0002] In the antenna system, the electric adjustment device contains various complex components. If these components are not shielded, the intermodulation index of the antenna system will decrease due to some nonlinear factors in the antenna system. The traditional electric adjustment device includes a metal shielding casing and a motor. The motor is installed in the metal shielding casing, and the motor is fixed in the metal shielding casing with metal screws and other mounting parts. The metal shielding casing can prevent components from affecting the antenna to a certain extent. The intermodulation index performance of the system. However, the main signal of the traditional antenna system is still mixed with clutter signals, and the performance of the intermodulation index cannot meet ...
