Double-frequency broadband wall-mounted antenna

Abstract

The invention relates to a double-frequency broadband wall-mounted antenna which comprises a reflecting plate, a low-frequency radiating element and a high-frequency radiating element, wherein the reflecting plate is provided with a feed network which feeds the low-frequency radiating element and the high-frequency radiating element; the feed network comprises a medium base plate, a low-frequencymatching network, a high-frequency matching network and diplexer, wherein the low-frequency matching network and high-frequency matching network are printed on the medium base plate by microstrip lines and respectively feed the low-frequency radiating element and the high-frequency radiating element and a diplexer is used for combining/shunting the low-frequency matching network and the high-frequency matching network; and the high-frequency radiating element comprises a half-wave symmetrical high-frequency oscillator, the low-frequency radiating element comprises a low-frequency oscillator, the high-frequency oscillator and the low-frequency oscillator are both realized in the form of the microstrip lines, an oscillator arm of the high-frequency oscillator presents a fan shape, and the low-frequency oscillator integrally presents an E shape. The antenna has the advantages of low profile, broad band, fine radiation performance index and the like.

AI Technical Summary

Benefits of technology

The present in this patented technology allows for smaller size but still improves radioactive efficiency by reducing the total amount of material needed on both sides of an electrically conductive element (E) compared to previous designs that had one side thicker or were made up entirely from metal wire instead of plasma coated glass fiber). This results in better radiating properties without adding too much weight.

Problems solved by technology

This patents discuss different types of wireless communication systems used inside buildings such as Wireless Local Area Network (WLAN) or Bluetooth® devices. These networks use electromagnetic waves with frequencies ranging from 2 GHz upwards towards 5GHz. To improve their efficiency, these signals should be transmitted over long distances without being distorted by interference caused by factors like walls and furniture. Existing methods involve placing an external device at certain points along the path where signal transmission takes place, resulting in increased complexity and cost compared to smaller versions of traditional wireline connections. Therefore there needs better ways to transmit data within specific bands while maintaining good radio wave propagation properties.
