Abstract

The invention provides a microstrip patch antenna. The microstrip patch antenna comprises a dielectric substrate; the radiation patch is arranged on the first surface of the dielectric substrate; the grounding plate is arranged on the first surface of the dielectric substrate, and a gap is formed between the grounding plate and the radiation patch; and the feed unit is arranged on the second surface of the dielectric substrate, and the feed unit is coupled with the radiation patch. According to the microstrip patch, the antenna impedance bandwidth of the microstrip patch is widened through the radiation patch and the grounding plate which are arranged on the dielectric substrate and the feed unit arranged on the other side of the dielectric substrate.

Description

technical field [0001] The invention belongs to the technical field of communication equipment, and in particular relates to a microstrip patch antenna. Background technique [0002] With the widespread popularization of family cars, the number of vehicles in the road transportation network has increased sharply, the road load has increased, and traffic accidents such as traffic jams, rear-end collisions, and collisions have occurred frequently. The construction of road interchanges and administrative orders have been used to solve traffic congestion problems. With little success. Intelligent Transportation System (Intelligent Transportation System, ITS) emerges in response to this situation, and has a remarkable effect in reducing traffic congestion and reducing the incidence of traffic accidents. The intelligent transportation system includes three parts: information collection system, information processing and analysis system and information release system. Among them, ...
