Broadband antenna

Abstract

The invention discloses a broadband antenna. The broadband antenna comprises a grounding layer, a feed microstrip line carried by the grounding layer, a radiation patch arranged on the same side of the grounding layer relative to the feed microstrip line and is separated from the feed microstrip line through an insulating dielectric layer, and a first L-shaped probe and a second L-shaped probe which are located in the insulating dielectric layer and parallel to each other; and the first L-shaped probe is composed of a first arm and a second arm, the second L-shaped probe is composed of a third arm and a fourth arm, the first arm and the third arm are arranged below the radiation patch and are parallel to the radiation patch, and the open ends of the second arm and the fourth arm are connected with the feed microstrip line. The broadband antenna provided by the invention has the advantages of small size, wide frequency band and high gain at the C wave band at the same time.

Description

Technical field [0001] The present invention relates to communication technologies, and more particularly, to a broadband antenna. Background technique [0002] C-band is the frequency band of 4.0GHz ~ 8.0GHz from the period of the first frequency band is employed in the satellite television broadcasting and various VSAT applications and have been widely used, C-band antenna is an antenna receiving C-band signals. [0003] The current C-band antennas generally parabolic antenna (commonly known as big pot), C-band antennas which occupy a large space, mounting and fixing of the presence of difficulty, it is generally difficult for the user to achieve a plurality of satellites received television program by installing a multi-seat antenna Planning . Based on this, a number of attempts to select a common scheme for producing C-band patch antenna structure, i.e. the energy feed structure coupled to the other side of the radiation patch of the patch antenna radiation patch through a di...
