Description

technical field [0001] The present invention relates to the technical field of antennas, and more specifically, to an antenna device and a method for using the same. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. [0003] With the rapid development of wireless communication technology, antennas, as an important part of wireless communication equipment, are key components that affect the overall performance of communication systems. They are widely used in systems such as global posi...

AI Technical Summary

Problems solved by technology

[0004] Although many traditional wireless communication antennas can work in multiple wireless frequency bands, their working frequency bands are very narrow and can only cover one working frequency band, and there are still requirements for large form size, high processing cost, high profile or machining accuracy High-level defects, and the radiation pattern will split when working at high frequency, which will affect the electromagnetic radiation characteristics and lead to problems such as a decrease in antenna gain

For example, the traditional bow-tie antenna is a planar structure of a biconical antenna with a large volume. Generally, a sheet-like printed vibrator is used. The arms of the antenna are triangular sheets spread out on the same plane, and a distributed parameter transmission line is formed between the two triangular sheets. , the ratio of the distributed inductance and capacitance extending outward from the feed end remains constant, so the characteristic impedance along the line remains unchanged, with a bandwidth limitation, and the size of the traditional bow tie antenna is related to the lowest frequency wavelength of the antenna’s working frequency band, the antenna does not add a guide In the case of the reflective structure, the antenna normal phase gain is low
