Abstract

The invention relates to a flat plate type miniature digital TV antenna which comprises a metal radiator which is the first surface binding of an insulating plate and a grounding metal element and a metal parasitic element which are connected with a second surface binding. The metal radiator is provided with a meandering curve part, the metal parasitic element is also provided with a meandering curve part corresponding to the position of the metal radiator, and the metal parasitic element increases the frequency width of an antenna receiver / radiation electromagnetic wave signal for promoting the efficiency of the digital TV signal.

Description

【Technical field】 [0001] The present invention relates to antennas for portable electronic devices such as mobile phones, notebook computers, and personal digital assistants, especially for receiving digital television antennas. 【Background technique】 [0002] There are a variety of antennas for receiving digital television signals, such as those disclosed in U.S. Patents U.S. 6,819,297, U.S. 6,639,555, U.S. 6,259,416, and Taiwan Patent No. I255589, No. I240451, No. M285154, and Taiwan Patent Publication No. 521455. [0003] Among them, Taiwan Patent Announcement No. 521455 discloses a planar miniaturized antenna for digital TV, including: a substrate, the upper and lower surfaces of which are respectively printed with copper foil to form a strip line; and a plurality of antennas, which are printed with copper foil The method forms Rampart Lines, which are respectively arranged parallel to the upper and lower surfaces of the substrate, cross-connected to the strip lines, and...
