Antenna device with multiple units generating different polarized signals
A recently filed patent (Publication Number: US20230307834A1) describes an antenna device with multiple antenna units and a feed-in line. The first antenna unit is positioned at a 90-degree angle to the second antenna unit, and the third antenna unit is also positioned at a 90-degree angle to the first antenna unit. The feed-in line crosses over each of the antenna units and is configured to turn them on and off. The first and second antenna units generate a first polarized signal, while the second and third antenna units generate a second polarized signal with different polarizations.
The antenna device is designed with a specific arrangement and configuration. The feed-in line extends along a certain direction, and the antenna units are arranged in order along this direction. The feed-in line consists of two portions, one crossing over the second antenna unit and the other crossing over the first and third antenna units. The first feed-in line portion is positioned between two terminals of the second feed-in line portion, and these terminals are opposite each other along the second direction.
The antenna device is also characterized by its dimensions. It generates a signal with a specific wavelength and has a first length along a certain direction, which is approximately 0.7 times the wavelength. It also has a second length along a perpendicular direction, which is approximately 0.5 times the wavelength.
The method of manufacturing the antenna device involves the placement of the antenna units and the feed-in line. The first antenna unit is disposed perpendicular to the second antenna unit, while the third antenna unit is placed parallel to the first antenna unit. The feed-in line is positioned to cross over all three antenna units and enable or disable them. The first and second antenna units generate a first polarized signal, while the second and third antenna units generate a second polarized signal with different polarizations.
In summary, this patent describes an antenna device with multiple antenna units and a feed-in line that controls their activation. The antenna units are arranged at specific angles and generate signals with different polarizations. The device is designed with precise dimensions and can be manufactured using a specific method.
