Novel wideband antenna with double rectangular rings

Abstract

The invention provides a novel wideband antenna with double rectangular rings. The novel wideband antenna with the double rectangular rings comprises an insulating substrate and a rectangular metal ring printed on the insulating substrate, the metal ring consists of an inner rectangular metal ring and an outer rectangular metal ring which are in a pair, a pair of feed portions used for feeding is arranged on one sides, which are combined into a whole, of the inner metal ring and the outer metal ring, and the other sides of the inner metal ring and the outer metal ring are in intersectional connection to form a matched antenna radiation loop portion. According to the scheme, the novel wideband antenna with the double rectangular rings has the advantages that the antenna can work within an ultra-wideband range through the inner rectangular metal ring and the outer rectangular metal ring which are paired, and the inner metal ring is designed according to a shape structure matched with high-frequency wavelength features, so that the antenna achieves a function of generating high-frequency signal radiation.

Description

technical field [0001] The invention relates to the technical field of television antennas, in particular to a novel broadband double rectangular loop antenna. Background technique [0002] Antennas are widely used by virtue of their ability to transform the propagating guided wave on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa, where the bandwidth is used as a measure of the effective work of the antenna The index of the frequency range, the value of which has a significant impact on the performance of the antenna. Traditional antennas increase the bandwidth of the antenna by using thicker metal wires, metal mesh cages, and a single component integrated with multiple antennas. However, these methods have defects such as too complex antenna structures or unstable performance.

Problems solved by technology

Traditional antennas increase the bandwidth of the antenna by using thicker metal wires, metal mesh cages, and a single component that integrates multiple antennas. However, these methods have defects such as the structure of the antenna is too complicated or its performance is unstable.

[0003] At present, with the development of modern wireless communication technology, various devices put forward higher requirements for the antenna's acceptance capability, but the existing antenna devices have the problem of insufficient bandwidth, which restricts the wide application of TV antennas and cannot meet the needs of consumers. needs of
