Technical field
The present invention relates to a kind of communication antenna, particularly to a kind of provide capability of fast response, there is altitude maneuver
The full-automatic log-periodic antenna of ability.
Background technology
The ultra broadband characteristic of log-periodic antenna is allowed to obtain widely should in shortwave, ultrashort wave, field of microwave communication
With.Its main structure is to be formed by as the assembly line of transmission line and the multipair radiating doublet being symmetrically arranged on assembly line.
The overall dimensions of antenna are related to its working frequency range, and assembly line axis to larger to size with the axis of oscillator.Generally
Oscillator axis to full-size be about antenna lowest operating frequency half wavelength, and gather bobbin thread to size be about
About half to 1 wavelength of antenna lowest operating frequency.Oscillator quantity is more, right up to tens.
Therefore, when Antenna Operation is in shortwave, ultrashort wave frequency band, because frequency is low, such antenna volume can be led to big, heavy
Amount weight.In actual use, particularly moving, motor-driven use when, how to realize the fast erecting of antenna and remove receipts, solved
Limit deposit, transport space is the two big targets that Antenna Construction Design must solve, realize, but between the two generally be in alternative,
