A Novel Broadband Dual Rectangular Loop Antenna

Abstract

The invention provides a novel broadband double rectangular loop antenna, which includes an insulating substrate and a rectangular metal ring printed on the insulating substrate. The metal ring is composed of a pair of rectangular inner and outer metal rings, wherein the One side of the inner and outer metal rings is integrated and provided with a pair of feeding parts for feeding, and the opposite side is cross-connected to form a matching antenna radiation circuit part; the present invention adopts the above-mentioned scheme Finally, the double rectangular loop antenna can work in an ultra-wide frequency bandwidth through a pair of antennas composed of inner and outer rectangular metal rings, wherein the inner metal ring is carried out by a shape structure that matches the high-end frequency wavelength characteristics. Designed to realize its function of generating high-end 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. [0003] At present, with the development of modern wireless communication technology, various devices put forward higher r...

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
