Problems solved by technology

Therefore, the size of the antenna needs to be equal to or greater than the length of the two slits having different lateral lengths and the length of the conductor between the two slits, making it difficult to miniaturize the antenna.
In addition, along with this, it is also necessary to consider the length of each feeder line extending from the branch portion of the feeder line to each slit portion or its routing position. As a result, the structure becomes complicated and the design may eventually become difficult.

Embodiment Construction

[0096] The antenna of the present invention uses two antenna element structures that can efficiently transmit and receive radio waves of a specific polarized wave component, and each of the two antenna element structures is arranged oppositely on the same plane of the antenna. The power supply point is set on one side only. In addition, the antenna of the present invention can adjust the resonance characteristics in two different frequency bands by adjusting the size of each antenna element structure, adjusting the position of the feeding point, or adjusting the combination of the two methods, and can efficiently transmit and receive by a single unit. Electric waves in two different frequency bands formed by specific polarized wave components. The two different frequency bands are not frequency bands for transmitting and receiving radio waves of a total of two frequency bands using harmonics of one frequency band.

Abstract

The invention provides an antenna and electrical equipment with the same. The antenna can individually and efficiently receive and transmit electric waves formed by specific polarized waves in two different frequency bands by virtue of a simpler structure. The antenna receives and transmits the electric waves of a plurality of frequency bands and is provided with a conductor, two slits and a power supply point, wherein the two slits are formed opposite to the conductor and provided with an open end respectively at opposite sides, and the poser supply point is formed only at a position above one of the two slits.

Description

technical field [0001] The present invention relates to an antenna corresponding to a communication system using radio waves formed of a specific polarized wave component, and to an antenna enabling efficient transmission and reception of radio waves in two frequency bands of the communication system, and an electrical appliance equipped with the antenna. equipment. Background technique [0002] Currently, there are many communication systems using radio waves formed of specific polarized wave components (vertical polarized waves, horizontal polarized waves, etc.), such as mobile communications such as mobile phones, and terrestrial TV broadcasting. Especially in mobile communication, radio waves formed of vertically polarized waves are often used in consideration of the influence of obstacles and the communication distance. Furthermore, with the increase in the capacity and speed of communication information in recent years, and the diversification of communication systems...
