Problems solved by technology
[0003] Since WiFi does not rely on the physical wired backbone network, its transmission rate is not as stable as that of the wired network, and it is susceptible to frequency interference, which significantly reduces the transmission rate.
In addition, although the high transmission rate of WiFi is relatively high, the required system overhead is also high, which will reduce the application layer bandwidth by nearly half, and will also significantly affect the speed.
When radio waves are transmitted, they will be interfered by radio waves in similar frequency bands. At the same time, during the transmission process, there will inevitably be refraction, reflection, diffraction and other phenomena. When encountering a barrier with strong shielding ability, the signal may even be unable to penetrate The situation seriously affects the transmission quality

The invention provides a high-gain omnidirectional array antenna comprising a substrate. A feed coupling line connecting a feed source, N dual-frequency radiation units arranged in an array along thelength direction of the feed coupling line, and n second high-frequency radiation units. Each dual-frequency radiation unit consists of a first high-frequency radiation unit and a low-frequency radiation unit. A second high-frequency radiation unit is arranged behind each dual-frequency radiation unit. The feed coupling line feeds power to the dual-frequency radiation units and the second high-frequency radiation units. The N first high-frequency radiation unit and the n second high-frequency radiation units form a high-frequency radiation array; and the N low-frequency radiation units form alow-frequency radiation array. According to the invention, the high gain at the double frequency bands of 2.4GHz and 5GHz is realized simultaneously; the 802.11n unit is supported to work simultaneously at the double frequency bands of 2.4GHz and 5GHz; and the actual rate of the 802.11n is increased substantially.
Description
technical field [0001] The invention relates to the technical field of antennas and communications, in particular to a high-gain omnidirectional array antenna. Background technique [0002] With the popularization of wireless mobile communication around the world, people's demand for obtaining information anytime and anywhere wirelessly is becoming more and more urgent. With its own advantages, WiFi technology has gradually been widely recognized and recognized. Whether it is corporate business or family life and entertainment, there is an increasing demand for it. WiFi technology has shown great application value and good development prospects. [0003] Since WiFi does not rely on a physical wired backbone network, its transmission rate is not as stable as that of a wired network, and it is susceptible to frequency interference, which can significantly reduce the transmission rate. In addition, although the high transmission rate of WiFi is relatively high, the required sy...
