Abstract

The invention discloses a small-sized vehicle-mounted GPS micro-strip slot antenna. The slot antenna comprises a medium substrate, a grounding plate located on the lower side surface of the medium substrate and micro-strip lines located on the upper side surface of the medium substrate. The micro-strip lines comprise a rectangular principal arm micro-strip line, also comprise a first left side arm micro-strip line and a second left side arm micro-strip line which are located at the left side of the principal arm micro-strip line and connected with the principal arm micro-strip line, and also comprise a first right side arm micro-strip line and a second right side arm micro-strip line which are located at the right side of the principal arm micro-strip line and connected with the principal arm micro-strip line. The first left side arm micro-strip line, the second left side arm micro-strip line, the right side arm micro-strip line and the second right side arm micro-strip line are rectangular micro-strip lines. A left side rectangular gap and a right side rectangular gap are formed in the grounding plate. The projection of the left side rectangular gap is located at the left side of the principal arm micro-strip line. The projection of the right side rectangular gap is located at the right side of the principal arm micro-strip line.

Description

technical field [0001] The invention relates to automobile antenna technology, in particular to a miniaturized vehicle-mounted GPS microstrip slot antenna. Background technique [0002] Common car antennas are columnar antennas, which are inconvenient to install, making the top of the car body protrude, which greatly affects the appearance, and the external antenna is often exposed to wind and sun, and has a low service life. Therefore, we need to install a The flat antenna with a wider width can overcome the defects of the traditional columnar antenna, and the flat antenna can be integrated on the roof of the car without being exposed, the appearance structure is good, and the service life can be improved. Studies in the past few years have shown that TEM Horns, patch antennas and slotted antennas can be used as ultra-wideband antennas. Among them, patch antennas have the advantages of low profile, light weight, easy integration and low manufacturing cost, and have potenti...
