Problems solved by technology

[0005] For general digital video broadcasting (Digital Video Broadcasting, DVB), the bandwidth coverage of traditional planar monopole antennas is mostly lower than 30%, so the transmission and reception effects of the antennas are not ideal
On the other hand, when it is necessary to switch between VHF (Very High Frequency) and UHF (Ultra High Frequency) frequency bands, the traditional planar monopole antenna is often used due to the limitation of bandwidth. Inconvenience

Embodiment Construction

[0065] See first Figure 2A , 2B , the two figures are schematic diagrams representing the first embodiment of the present invention. The monopole antenna of the present invention can be used for wireless signal transmission within a specific frequency range, and it mainly includes a substrate S, a ground metal G, a first sleeve G1, and a second sleeve G2 , a first radiator R1 , a second radiator R2 and a cable W. The ground metal G and the first radiator R1 are formed on the surface S1 of the substrate S, wherein the first radiator R1 is located between the first and second sleeve structures G1 and G2, and faces a first direction (Y-axis direction) extend. In particular, the above-mentioned second radiator R2 is a conductor that can stretch along the Y-axis direction, wherein the second radiator R2 is connected to a connecting portion RC at the end of the first radiator R1, and the connecting portion RC is adjacent to the substrate S edge, and the above-mentioned second r...

Abstract

This invention relates to a single-pole antenna used in transmitting radio signals including a base plate, an earth metal, a first sleeve structure, a second sleeve structure, a first radiator, a second radiator and a cable, in which, said two sleeve structures are formed on the base plate and are connected with the earth metal and extend towards the first direction from a side edge of the earth metal, said radiator is formed on the base plate having a feed-in end and a connection part, which is adjacent to the edge of the base plate, said second radiator is connected with the connection partand extends to the first direction to project over the edge of the base plate, said cable is connected with the feed-in end to conduct radio signals. This invention can increase frequency width, reduce the size and increase the transmission efficiency of VHF frequency band and cover the UHF / VHF at the same time.

Description

technical field [0001] The present invention relates to a monopole antenna, in particular to a monopole antenna applicable to UHF frequency band and VHF frequency band. Background technique [0002] With the rapid development of wireless communication and the trend of miniaturization of communication products, some embedded micro-antennas have emerged as the times require. At present, the more commonly used micro-antennas include chip antennas (chip antennas) and planar antennas (planar antennas). antenna) and so on. Generally speaking, these types of antennas have the characteristics of small size, among which common chip antennas are ceramic chip antennas (ceramic chip antennas) made of co-fired ceramic technology (LTCC), and there are many planar antenna designs, such as micro Strip antenna (microstripe antenna), printed antenna (printed antenna) and planar inverted F antenna (Planar Inverted FAntenna, PIFA), etc., these antennas are widely used in wireless terminals suc...
