Problems solved by technology
For example, the frequency range of country A may be between 174MHz to 230MHz and 470MHz to 600MHz, the frequency range of country B may be between 174MHz to 230MHz and 500MHz to 700MHz, and the frequency range of country C may be 174MHz to 230MHz and 550MHz to 860MHz. Therefore, in order to adapt to the reception of TV signals in the frequency ranges such as 174MHz to 230MHz and 470MHz to 860MHz, it is a big challenge to design an antenna that can receive TV programs covering a wide range of frequencies.
At the same time, different TV programs use different frequency ranges. Therefore, if the antenna cannot cover the frequency range of all TV programs, it will be inconvenient for users to receive different TV programs during use.
[0003] At present, there are also some TV antennas on the market that can receive the above-mentioned wider frequency ranges, such as a retractable antenna, which can be adjusted to change its extension length to adapt to different frequency ranges, but users need to Repeated adjustments to achieve the antenna length that matches the frequency of the TV program you are watching is a bit cumbersome to use
At the same time, there is also a flat panel antenna made of a printed circuit board on the market. Although the flat panel antenna is suitable for a specific frequency range according to design requirements, its application frequency band is extremely narrow. The current printed circuit board antenna does not Unable to achieve wide frequency band such as 470MHz to 860MHz signal reception capability

The invention provides a sliver paste printed double-wideband antenna comprising a substrate, an insulating layer, a first signal feed-in portion, a second signal feed-in portion, a first radiating unit, a second radiating unit, a third radiating unit and a fourth radiating unit. The insulating layer, the first signal feed-in portion, the second signal feed-in portion, the first radiating unit, the second radiating unit, the third radiating unit and the fourth radiating unit are provided on the upper surface of the substrate. The first signal feed-in portion and the second signal feed-in portion are symmetrically provided on one side of the bottom of the substrate. The first radiating unit is in a concentric ring structure formed on the insulating layer and is connected with the first and second signal feed-in portions. The second radiating unit is formed on the insulating layer and connected with the first and second signal feed-in portions. The third radiating unit is formed on the insulating layer and connected with the first and second signal feed-in portions. The fourth radiating unit is independently formed on the insulating layer on the other side, opposite to the bottom of the substrate. The sliver paste printed double-wideband antenna has the greatest advantage that the antenna has a broadband, electromagnetic signals can be effectively radiated and received, and the antenna has the broadband feature.
Description
technical field [0001] The invention relates to the technical field of printed flat panel antennas, in particular to a silver paste printed dual broadband antenna. Background technique [0002] With the development of society and the continuous improvement of media communication technology, TV programs have become more and more popular. Currently, due to the slightly different frequency ranges used by the screens of TV program signals broadcast in various countries. For example, the frequency range of country A may be between 174MHz to 230MHz and 470MHz to 600MHz, the frequency range of country B may be between 174MHz to 230MHz and 500MHz to 700MHz, and the frequency range of country C may be 174MHz to 230MHz and 550MHz to 860MHz. Therefore, in order to adapt to receiving TV signals in the frequency ranges such as 174MHz to 230MHz and 470MHz to 860MHz, it is a big challenge to design an antenna that can receive TV programs covering a wider frequency range. At the same time...
