Technical Field

[0001] The utility model relates to the technical field of communications, in particular to an umbrella-shaped medium- and short-wave antenna. Background Art

[0002] Monitoring the quality and effect of open-circuit transmission of radio and television has always been one of the important businesses of the radio and television monitoring and supervision industry. It is necessary not only to understand the order of radio waves and network channels in the radio and television bands in real time, but also to grasp the dynamics of various illegal radio stations, black radio and gray radio on my country's radio. No matter how the monitoring is carried out, a pair of medium and short wave antennas with good performance are essential.

[0003] According to electromagnetic wave transmission theory, electromagnetic waves can only be transmitted or emitted to the maximum extent when the antenna size and the pre-transmitted carrier signal are of the same order of magnitude. However, the medium and short wave frequencies are generally 526.5KHz to 30MHz, the frequency band is too low, and the wavelength is too long, resulting in the required transceiver antennas being often bulky, especially when used for field mobile measurements, which are difficult to set up and inconvenient to carry. To solve the difficulty in setting up antennas, existing medium and short wave antennas usually use smaller physical sizes and impedance matching, which results in high prices, narrow operating frequency bands, poor quality factors, and weak anti-electromagnetic interference capabilities, limiting the development of monitoring and regulatory services.
