Embodiment Construction

[0014] Home audio-visual equipment with wireless transmission function includes a functional audio-visual gateway integrating wireless routers, network storage and digital media conversion, antennas for transmitting or receiving signals and 802.11X (X refers to a, b, g, etc.), and audio-visual gateways One or more digital media adapters that communicate through an antenna. The antenna is a smart antenna, capable of receiving and transmitting (or only supporting) single-channel and multiple-channel radio frequency signals, and the frequency meets the requirements of 802.11x.

[0015] Smart antennas are divided into two categories: multi-beam smart antennas and adaptive array smart antennas, referred to as multi-beam antennas and adaptive array antennas. The adaptive array antenna generally adopts a structure of 4 to 16 antenna elements, and the distance between the elements is 1 / 2 wavelength. Array elements are distributed in linear, circular and planar forms. The adaptive ar...

Abstract

The invention relates to an antenna applied to a household image and sound apparatus having a wireless transmission function, which provides a household image and sound apparatus having the wireless transmission function, comprising an antenna for transmitting and receiving signal, which is an intelligent antenna utilizing a digital signal to process the technology and generate space orienting wave beams, the frequency of which satisfies the requirement of 802.11x. Comparing to a common antenna, the intelligent antenna according to the invention can eliminate the affect of common channel disturbance(CCI), multi address interference and multi path decadent.

Description

【Technical field】 [0001] The invention relates to an antenna, in particular to an antenna applied to home audio-visual equipment with wireless transmission function. 【Background technique】 [0002] Home audio-visual equipment with wireless transmission function includes a functional audio-visual gateway integrating wireless routers, network storage and digital media conversion, antennas for transmitting or receiving signals, and 802.11X (X refers to a, b, g, etc.) network cards, and audio-visual The gateway communicates with the digital media adapter through the antenna, and the audio-visual gateway can communicate with other audio-visual gateways or digital media adapters through the 802.11X network card and antenna. Since the transmission power and receiving sensitivity of the 802.11x network card are limited, the use of general antennas will affect the transmission distance and quality. On the other hand, there are many spectrums in the air and multipath interference of ...
