Abstract

The invention discloses a novel composite umbrella-shaped micro-strip vibrator. An angle is formed between each umbrella-shaped vibrator arm (3) and the grounded plane (6), and the umbrella-shaped vibrator arms (3) are symmetrically arranged at two sides of a vertical vibrator arm (2); parasitic rods (4) are vertical to the grounded plane (6), and two parasitic rods (4) are symmetrically arranged at two sides of the vertical vibrator arm (2); the umbrella-shaped vibrator arms (3), vertical vibrator arm (2) and parasitic rods (4) are located on one lateral surface of a medium substrate (1), and a Balun impedance converter (5) is located at the other lateral surface; the vertical vibrator arm (2) and Balun impedance converter (5) are connected with a coaxial joint (7). The novel composite umbrella-shaped micro-strip vibrator combines the umbrella-shaped vibrator with the composite vibrator and is realized through the micro-strip mode, the best broadband matching is realized, and the wide angle coverage is satisfied; within 25% relative bandwidth, the input standing wave VSWR is less than 1.3, and the directional diagram is capable of meeting antenna scanning requirements; the wave beam at the surface E is 95.3 degrees in width, the wave beam at the surface H is 115.6 degrees, and the width completely meets the technology requirements.

Description

technical field [0001] The invention relates to a radar microstrip printed dipole antenna, in particular to a novel composite umbrella-shaped microstrip dipole. Background technique [0002] The beam width of the radiation unit in the two-dimensional phased array system radar is small, and the matching is difficult. The quality of its performance will directly affect the performance of the radar antenna. The wide bandwidth angle matching of the radiating element creates conditions for realizing the radar with low sidelobe and small loss of scanning gain. [0003] At present, the main forms of the oscillator radiation unit mainly include umbrella oscillator and composite oscillator. [0004] Umbrella oscillators are in the form of figure 1 As shown, the umbrella-shaped half-wave oscillator is a half-wave oscillator whose arms are perpendicular to the ground plane to form a certain angle, and it has a wide-angle pattern coverage performance. During the design process, both ...
