Problems solved by technology
[0005] The purpose of the present invention is to provide a dual-band broadband tie antenna using self-similar feeding technology, which aims to solve the narrow-band problem caused by the use of multiple resonant structures to achieve multi-frequency operation in existing dual-band broadband antennas
Due to the characteristics of the resonant structure itself, the existing antennas implemented by this method have the characteristics of narrow band, that is, they cannot meet the multi-band work requirements of multiple communication systems and different standards.

The invention discloses a double-frequency broadband bowtie antenna adopting a self-similarity feed technology. The whole antenna includes an upper-layer metal and a lower-layer metal. The upper-layer metal and the lower-layer metal cover the two faces of a dielectric slab respectively. A feed structure is a metal stripe-shaped line. A self-similarity feed structure is a bowtie-shaped metal sheet and includes two symmetrical trapezoid metals and a rectangular metal stripe-shaped line connected directly with a feed line. A parasitic radiating unit is a pair of symmetrical rectangular metal stripe-shaped lines which are designed at the two sides of the bowtie-shaped feed structure. The parasitic radiating unit includes two metal lines. A bowtie-shaped gap etched on the floor is a gap similar with the self-similarity feed structure. The gap includes two trapezoid gaps and a rectangular gap. The double-frequency broadband bowtie antenna adopting the self-similarity feed technology adopts the self-similarity feed structure which is more novel compared with the prior feed structures; and the antenna is capable of covering all frequency bands needed in WLAN and WiMAX communication so that compared with the prior antennae, the double-frequency broadband bowtie antenna has a double-frequency broadband characteristic.
Description
Technical field [0001] The invention belongs to the field of communication technology, and particularly relates to a dual-frequency broadband bow tie antenna adopting self-similar feeding technology. Background technique [0002] As an important result of the development of modern technology, communication technology is now an indispensable part of our daily lives. However, the frequency interference and compatibility problems brought by the technical basis of the central carrier among various communication standards have become increasingly prominent, and have been unable to meet the increasing requirements for high-speed access; on the other hand, future wireless networks will not only include human-to-human communication , And includes the communication network between people and terminals and terminals. This is actually the content of ubiquitous wireless communication (PWC), that is, the ability to interact with other wireless terminals at any time and anywhere. For these up...
