Abstract

The invention relates to a multi-channel enhanced WIFI transmitting and receiving device. The device comprises a high-gain antenna device, and more than two equal wireless hotspot devices, band-pass filtering devices, frequency shifting devices and antenna switching devices which are connected in sequence, and the high-gain antenna device comprises a substrate and more than two dual-polarization yagi antennas arranged on the substrate; according to the dual-polarization yagi antenna, the novel reflector and the active oscillator are designed, a dual-polarization structure is adopted, polarization loss of signal transmission can be reduced, an F-B resonant cavity can be formed by the F-B covering layer and the plane where the first end of the antenna axial rod is located, electromagnetic waves radiated by the antenna are overlapped in the resonant cavity in an in-phase mode, the radiation gain of the antenna is improved, and the radiation efficiency of the antenna is improved. The WIFI signals are moved to the low frequency band and then transmitted out, the coverage range of the WIFI signals can be increased, and the multi-channel enhanced WIFI transmitting and receiving device comprises a multi-input and multi-output signal transmission channel, so that the use reliability is high.

Description

technical field

[0001] The present application relates to the field of wireless technology, in particular to a multi-channel enhanced WIFI transceiver. Background technique

[0002] WIFI is a wireless LAN technology based on the IEEE 802.11 standard, which improves the interoperability between wireless network products based on this standard. WIFI is a short-distance wireless technology, which has the advantages of fast transmission speed, low transmission power and no need for wiring. It can meet the needs of personal and social informatization. In the case of weak signals, the bandwidth can be automatically adjusted to effectively ensure the stability of the network. sex and reliability.

[0003] The coverage of the WIFI signal transmitted by the traditional WIFI signal transmission device is limited, and the user cannot receive the WIFI signal in an area beyond the coverage of the WIFI, which affects the normal use of the user and has low reliability. Contents of the i...
