Wireless electronic product with step-type wideband antenna

Abstract

The invention discloses a wireless electronic product with a step-shaped wideband antenna. A printed circuit board is arranged in the wireless electronic product, the top surface, which is near the central position, of the printed circuit board is provided with a signal transceiving circuit, a conducting wire is extended out from the signal transceiving circuit to form a signal wire, the top surface of the printed circuit board is provided with a wideband antenna, the wideband antenna extends from the edge of the printed circuit board to the central position to form the antenna of which both sides are gradually reduced in a symmetrical step shape, and a micro-strip feeder extends from one end which is far away from the edge, and is connected with the signal wire. The current generated by the micro-strip feeder due to inductive effect can flow along both sides of the wideband antenna in a step-shaped winding route to ensure that the current can be evenly distributed on the wideband antenna, and effectively reduce the inductive effect of the micro-strip feeder, further to ensure that the distance between both ends of the wideband antenna is smaller than that of the prior bell-shaped antenna under the condition of approximate frequency width with that of the bell-shaped antenna to effectively achieve the aim of antenna miniaturization.

Description

technical field [0001] The present invention relates to a wireless electronic product, especially a wireless electronic product with a stepped broadband antenna on a printed circuit board, and specifically relates to a wireless electronic product with a stepped broadband antenna. Background technique [0002] As the current wireless electronic products produced by various companies are all developing in the direction of shortness and lightness, the space in the casing of the wireless electronic product is greatly reduced, and the area reserved for the antenna on the printed circuit board of the wireless electronic product becomes smaller. Therefore, the R&D personnel of various companies try to print antennas of different shapes such as circular and polygonal shapes on the printed circuit board, in order to find the most suitable shape, size, lower cost and easy to adjust the physical characteristics of the antenna. However, none of them can design antennas that meet the afo...
