Embodiment Construction

[0021] Such as figure 1 Shown is the superstructure of the double-row rectangular S-shaped pole antenna. The size of the upper dielectric substrate 1 is H1 (18mm) × L1 (60mm) × D1 (1mm), the relative permittivity of the upper dielectric substrate 1 is 2.2, and the compound pole antenna 4 is located at the lateral midline of the upper dielectric substrate 1, and the composite The pole antenna 4 is a strip-shaped structure, which is divided into front end, middle end and end. The length of the front end is L2=16mm, the width H2=1.4mm, the length of the middle end is L3=26mm, the width H3=0.8mm, and the length of the end is L2=16mm , width H2=1.4mm. The ends of the compound pole antenna 4 are symmetrically distributed in two layers and six groups of double-row rectangular S-shaped resonant structures 3 are arranged periodically, three groups on each side, and each group has a double-row rectangular S-shaped resonant structure 3, and the metal strip 5 is connected with the compos...

Abstract

The invention discloses a double-row moment S-shaped pole antenna which comprises an upper layer dielectric substrate (1) and a lower layer dielectric substrate (2) jointed together. The double-row moment S-shaped pole antenna also comprises double-row moment S-shaped resonance structures (3) and a composite pole antenna (4), wherein the double-row moment S-shaped resonance structures (3) are symmetrically fixed on two sides of the tail end of the composite pole antenna (4); and the composite pole antenna (4) is connected with each double-row moment S-shaped resonance structure (3) through metal strips (5). According to the combination of the double-row moment S-shaped resonance structures (3) and the composite pole antenna (4), the magnetic permeability can be increased, the electromagnetic wave resonance strength can be enhanced in a specific frequency range, the antenna gain is increased and the return loss is reduced.

Description

technical field [0001] The invention belongs to the field of microstrip antennas, in particular to a double-row rectangular S-shaped pole antenna. Background technique [0002] Left-handed material (LHM) is a new artificial electromagnetic medium with periodic structure that emerged in the late 1990s. It also has a dielectric constant and permeability The double-negative material is negative, that is, when the electromagnetic wave propagates in this dielectric material, the electric field, magnetic field and wave vector follow the left-hand rule, so it is called left-handed material (or negative refraction material). As a new type of artificial electromagnetic material, it has attracted great research interest in recent years. As early as 1968, V.G.V eselageo theoretically studied the abnormal electromagnetic phenomenon in LHM; in 2000, Smith et al. produced a negative refractive index medium in the microwave segment for the first time in the laboratory. The anomalous ...
