Embodiment Construction

[0021] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0022] The invention relates to a low-profile end-fire antenna with an all-metal structure. It has the characteristics of simple structure, low profile and low manufacturing cost. According to the design schematic, a specific embodiment of an all-metal low-profile end-fire antenna applied to 5GHz is given, which is described below in conjunction with the accompanying drawings:

[0023] refer to figure 1 , the endfire antenna includes a metal strip 1 . The metal strip 1 is parallel to the metal floor 5 to form a microstrip line of the air medium. Along the length direction of the metal strip 1, half-mold patch radiating units are periodically arranged on both sides thereof. The half-mold patch radiating unit is composed of a metal sheet 1 , a metal sheet 2 3 and a metal wall 4 . The metal strip 1, the first metal sheet 2, and the second meta...

Abstract

A low profile end-on-fire antenna of an all-metal structure comprises a metal floor; a metal strip forming a feeding microstrip line structure together with the metal floor; and half-mold patch radiating elements arranged periodically along the microstrip line, on which there are metal walls formed by stamping. The antenna is composed of an all-metal structure. The use of air as the medium can achieve good end-on-fire effect. The antenna is characterized by low profile, simple structure and low manufacturing cost, and is convenient for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to an end-fire antenna, in particular to a low-profile end-fire antenna with an all-metal structure. Background technique [0002] An endfire antenna is an antenna in which energy starts from a feed source and radiates along the direction in which the antenna extends. There are many types of end-fire antennas, and the styles are relatively rich. It can be an independent structure, such as Yagi antenna, axial mode helical antenna, dielectric rod antenna, logarithmic periodic antenna and conical helical antenna, etc., or an array composed of multiple independent antenna units. [0003] Endfire antennas are widely used in both military and civilian fields. Especially in some application scenarios with limited space size, such as the top of an airplane or a car, there is a great demand for low-profile end-fire antennas. The low-profile nature requires the end-fire antenna to be mounte...
