Antenna element and antenna system using the same

Abstract

The invention relates to an antenna element which comprises a first sheetmetal; a second sheetmetal electrically connected to a specific level; a third sheetmetal connecting the first sheetmetal and the second sheetmetal; and a feed point positioned on the first sheetmetal; wherein the first sheetmetal has at least one bending, a first broadside and a second broadside, the first broadside is connected to the third sheetmetal, the second broadside faces the second sheetmetal yet not electrically connected to the second sheetmetal, the feed point is positioned at the second broadside, an object is arranged between the first and the second sheetmetals, a dielectric constant of the object is substantially equal to that of the air, and the distance (w,h) of the first broadside and the second broadside is determined by the lowest operation frequency fo the antenna element. The antenna element is formed by folding or combining the sheetmetals, therefore, the dimension of the antenna element can be reduced, and the manufacturing process can be simplified.

Description

technical field [0001] The present invention relates to an antenna element and an antenna system using the antenna element, in particular to a broadband antenna element which can be embedded in a system and a broadband antenna system using the broadband antenna element. Background technique [0002] The most common form of bridging point antennas currently used in wireless broadband routers / hubs is a dipole antenna with a plastic / rubber sleeve on the periphery, which is mainly placed on one side of the device, and the antenna is exposed above the product case. When the communication technology of multi-antenna system is used, especially when the number of antennas is more than two units, the antennas are easily damaged by external forces, and they also take up a lot of space and affect the visual effect. figure 1 It is a schematic diagram of a broadband router 100 in the prior art. Such as figure 1 As shown, the broadband router 100 has antennas 101, 103, and 105, but the ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned antennas all need an additional plastic / rubber sleeve to be sleeved on the periphery of the antenna, which increases the manufacturing cost and complexity of the antenna

In addition, this type of antenna cannot be hidden in a general wireless broadband router / hub device, that is, the antenna must be exposed outside the casing, which greatly reduces the aesthetics of the product appearance
