Title: SECTIONAL-LOAD SHORTWAVE ANTENNA CAPABLE OF AUTOMATICALLY ADJUSTING ANTENNA OSCILLATOR
Abstract:
Provided is a sectional-load shortwave antenna capable of automatically adjusting an antenna oscillator, comprising a main rod body as well as a support bracket arranged on the bottom of the main rod body and a T-shaped oscillator arranged on the top of the main rod body; a sensor is arranged at the connection of the main rod body with the T-shaped oscillator; the sensor is cylindrical and one end is closed and the other end is open; the T-shaped oscillator passes through the center hole of the closed end and engages and connects with the sensor and is inside its cylindrical shape; in order to solve the problem of improving frequency characteristics, the present invention adds a sensor to improve and widen the overall frequency characteristics; in order to widen the operating frequency of the antenna, reactance and resistance components are connected at sections of the antenna. An asymmetric vertical antenna may be analyzed as a terminal open circuit when viewed from the bottom up. A terminal open circuit has certain impedance frequency characteristics. When an oscillator of a certain size is operating within a wide frequency range, its bandpass may contain several series resonance frequencies and parallel resonance frequencies.
