An omnidirectional antenna

Abstract

An omnidirectional antenna, relating to the field of communication antenna technology, includes a support, a tapered radiating cone, a feed line, and a radome. The support is constructed from a molded substrate, with the antenna body integrally molded with the ground plane, resulting in a compact structure requiring no additional assembly. The tapered radiating cone is mounted on the support, comprising a lower cone structure and an upper tapered structure. The cone structure expands the bandwidth, while the tapered structure reduces the antenna size. The feed line connects to the tapered radiating cone for signal transmission. The radome covers the exterior of the support for enhanced protection. Laser engraving is used to etch the tapered radiating cone's circuitry onto the inner surface of the support, achieving precise forming of the conductive lines and eliminating the need for soldering. Its advantages include: expanded operating bandwidth and stable VSWR, supporting ultra-wideband communication; miniaturization and low profile of the support; integrated design eliminating assembly processes, improving product consistency and yield; and laser engraving reducing manufacturing costs, making it suitable for integration into smart devices.
