Technical Field
The utility model relates to a Wi-Fi signal reception field specifically is a receiving antenna of reinforcing Wi-Fi signal.
Background
An antenna is an energy converter that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is used for the same basic characteristic parameters for transmission or reception, as is the case with Wi-Fi antennas.
At present, a wireless router and Wi-Fi receiving equipment all use a traditional Wi-Fi antenna, the antenna is only a medium, a transmitting terminal antenna converts high-frequency current or guided wave into radio wave-free electromagnetic wave to radiate to the surrounding space, and the principle is as follows:
at the receiving end, the radio waves are converted into high-frequency currents or guided waves by the receiving antenna and transmitted to the receiver via the feed device. The conventional antenna used by the user has the common problems that the experience of surfing the internet is poor after a Wi-Fi signal penetrates through a wall, after the antenna penetrates through two walls, Wi-Fi signals of terminal equipment such as a mobile phone and the like display 2-3 grids of signals, because the PA is additionally arranged on the conventional wireless router, the signal amplification is added at a transmitting end, the signal display is realized, the internet cannot be surfed, the experience is very poor, and the problem that a terminal user complains about the Wi-Fi signal display is often caused.
The reason for this is also above the reception of the signal. This is a problem and disadvantage of current Wi-Fi antennas-poor reception. The common method is only to improve the transmission, and the gain, the efficiency and the VSWR are all well adjusted, but the user internet surfing experience cannot be improved.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a receiving antenna of reinforcing Wi-Fi signal.
