Description

Technical Field

[0001] The utility model relates to the technical field of communication, in particular to a broadband wire antenna. Background Art

[0002] Medium and short wave channels are not restricted by network hubs, relay conditions, and personnel factors. They only rely on ionosphere and ground wave propagation and have strong anti-destruction capabilities. However, due to factors such as the narrow frequency band and complex structure of the transmitting and receiving antennas, this frequency band is currently only suitable for broadcasting and the transmission of specific information. Generally speaking, the antenna bandwidth mainly depends on the frequency characteristics of various electrical indicators of the antenna, such as the pattern bandwidth, gain bandwidth, input impedance bandwidth, polarization bandwidth, and other factors. The means to solve the broadbandization of antennas have obvious defects, such as the mechanical and electrical combination, the use of carefully designed antenna mechanical structures, and the problem of complex structure; inserting impedance elements or matching networks inside the antenna has the disadvantage of reducing the antenna transceiver efficiency; using a pair of antennas in a multi-mode working mode, there is a problem of high cost; frequency-independent antennas have antenna polarization problems; wide-band traveling wave antennas have the problem of large footprint. It is precisely because of the insurmountable difficulties of various types of medium and short wave frequency band antennas that related research and practice have been slow to progress and have been difficult to make major breakthroughs. Therefore, there is an urgent need for a broadband wire antenna to solve the problems of narrow operating frequency band, large footprint, low transmission and reception efficiency, complex structure, and difficulty in installation of common antennas on the market.

The electronic component box contains a compensation circuit and a load circuit composed of a capacitor and a resistor. The balun box contains a coil, which is used to match the impedance of the square ring antenna and suppress common mode current through a specific winding method, wherein the winding density, number of turns and length of the coil match the circumference of the square ring formed by the metal connecting rod.

[0006] As a further solution of the utility model: multiple two-type metal connecting rods are movably connected through a rivet structure, so that the antenna as a whole is movably connected through the rivet structure, and supported by a non-metallic support rod, so that the antenna as a whole is in a catenary state, and rapid storage and support are achieved, and the reception and transmission of medium and short wave broadcast signals are completed.

[0010] As a further solution of the present invention: the number and length of metal connecting rods are determined according to the frequency of the pre-transmitted and received signals. This solution uses hard metal connecting rods, but depending on the specific situation, the metal connecting rods can use flexible metal materials, such as plastic-coated steel wire, high-strength silver-plated PU wire and other materials, which are not only lightweight, but also rust-resistant, tensile-resistant and aging-resistant.
