AI Technical Summary

Benefits of technology

This technology allows for better wireless communications even if there are obstacles near it's location because an outside antenna controls its own internal circuits instead of just sending out high power analogue waves from inside.

Problems solved by technology

This patented describes how wireless signals can be affected if they get wet during rain due to snow falling on them over time. When this happens, the reception of certain frequencies becomes worse than usual because these waves have less strength at those specific points where their intensity falls below what was expected from normal levels. To solve this problem, some systems use special hardware components called radiosets (which work together with other electronic devices) placed near each end of the receiving device's antennas. These radioset elements help improve the accuracy of received signals even after being exposed to water vapor.

Embodiment Construction

[0024] To improve as figure 1 In the traditional antenna system 100 shown, when the weather is bad or the shelter seriously affects the communication quality, the microcontroller 140 cannot identify which one of the first built-in antenna 110 or the second built-in antenna 120 has better communication quality. Preferably, the microcomputer signal MS sent by the microcontroller 140 controls the switching circuit 130 to randomly switch between the first built-in antenna 110 and the second built-in antenna 120 to transmit and receive radio frequency signals RFS. In other words, the traditional antenna system 100 cannot effectively switch to the built-in antenna with better communication quality when the weather is bad or the shelter seriously affects the communication quality. The technical solution for effectively improving the communication quality provided by the embodiments of the present invention will be further described below.

Abstract

The invention relates to an antenna system of switchable external antennas. The antenna system comprises a plurality of built-in antennas, a switching circuit, an external antenna control circuit anda first external antenna connector. The built-in antennas include at least a first built-in antenna and a second built-in antenna, and the first built-in antenna and the second built-in antenna are used for receiving or transmitting radio frequency signals. The switching circuit is used for switching between the first built-in antenna and the second built-in antenna to receive or transmit the radio frequency signals. The external antenna control circuit is used for transmitting a control signal to the switching circuit. When the first external antenna connector is connected with an external antenna, the external antenna control circuit transmits the control signal of a first logical electrical level to the switching circuit, and the switching circuit switches to the external antenna to perform the function of receiving or transmitting the radio frequency signals.
