Embodiment Construction
[0023] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0024] refer to figure 1 , figure 1 It is a schematic diagram of an embodiment of a built-in antenna according to the present invention. The built-in antenna 15 includes a plate 151, an antenna vibrator 152, a feed point 153, and a mounting hole 154. The antenna vibrator 152 is fixedly placed on the plate 151, and the antenna vibrator 152 transmits and receives electromagnetic signals. The frequency band is 2.4G-2.5GHz.
[0025] The feeder line of the built-in antenna 15 is the signal transmission line of the radio and television network, that is, the coaxial line, and the impedance value of the coaxial line is 75Ω. . The built-in antenna 15 is used to generate a WiFi hotspot for transmitting and receiving WiFi wireless signals, and the frequency band of the radiated electromagnetic signals is 2.4G-2.5GHz. The mat...

The invention discloses an embedded antenna, a WOC (WLAN OVER CATV) device and a signal transmissions system. The signal transmission system comprises a first signal distribution device, the WOC device and a coaxial line, wherein the first signal distribution device comprises a first input port, a distributor and a plurality of first output ports; the WOC device comprises a signal input port, a shunt, a TV signal output port and the embedded antenna; and the first output ports are electrically connected and the signal input port through the coaxial line. The signal transmission system distributes a mixed signal of one path of input network signal and TV signal into a plurality of paths of mixed signals, and a plurality of specified areas are under the coverage of a wireless network at the same time, so that the problems of existence of signal dead zones and signal instability during conventional wireless coverage are solved; meanwhile, network signal resources can be configured and utilized well; and the use efficiency of the network signal resources is increased.
Description
technical field [0001] The invention belongs to the field of radio and television and network equipment, and in particular relates to a built-in antenna, a WOC device and a signal transmission system. Background technique [0002] At present, when using the Internet, a wireless router is usually used to generate a WLAN signal, which is provided to a terminal such as a computer or a smart phone to connect to the network. When used in a living room or a company, the wireless signal usually needs to pass through the wall or be used normally at a long distance. Due to the wireless radiation capability of the wireless router, there are often problems such as low wireless signal strength and poor stability. [0003] The radio and television network transmits radio and television signals through the coaxial line, which has the characteristics of good stability and strong anti-interference ability, and due to the layout of the radio and television network, the radio and television s...
