Embodiment Construction

[0025] Please refer to figure 1 , figure 1 It is a schematic diagram of a broadband antenna 10 according to an embodiment of the present invention. The broadband antenna 10 includes a ground component 100 , a radiator 102 , a matching adjustment component 104 , a feeding component 106 and a short circuit component 108 . The grounding component 100 is electrically connected to the ground terminal for providing grounding. The radiating element 102 is composed of a first radiating portion 1020 and a second radiating portion 1022 respectively extending in different directions and having different lengths to provide two different radiation frequency bands. One end of the matching adjustment component 104 is electrically connected to the junction of the first radiating portion 1020 and the second radiating portion 1022 , and the other end is electrically connected to the feed-in component 106 . The feed-in component 106 is electrically connected between the matching adjustment co...

Abstract

Disclosed is a broadband antenna. The broadband antenna comprises a grounded component, a radiation part, a matching and regulating component, a feed component and a short-circuit component. The grounded component is electrically connected to a ground. The matching and regulating component is electrically connected to the radiation part. The feed component is electrically connected between the matching and regulating component and the grounded component and is used for receiving feed signals. The short-circuit component is electrically connected between the matching and regulating component and the grounded component. Width of the matching and regulating component is related to bandwidth of the broadband antenna. Bandwidth of the antenna is added, especially low frequency bandwidth, so that the broadband antenna is suitable for a wireless communication system with broadband requirements.

Description

technical field [0001] The invention relates to a wideband antenna (wideband antenna), in particular to a wideband antenna which increases the bandwidth of the antenna through a matching adjustment component. Background technique [0002] Antennas are used to transmit or receive radio waves to transmit or exchange radio signals. Generally, electronic products with wireless communication functions, such as notebook computers, personal digital assistants (PDA), etc., usually access wireless networks through built-in antennas. Therefore, in order to allow users to access the wireless communication network more conveniently, the bandwidth of the ideal antenna should be increased as much as possible within the allowable range, while the size should be reduced as much as possible to match the trend of shrinking the size of portable wireless communication equipment. Antennas are integrated into portable wireless communication equipment. In addition, with the evolution of wireless...
