Problems solved by technology

However, the antennas currently used in indoor WLAN and WIMAX either have a large size and a narrow bandwidth with a reflection coefficient of 10dB, or they do not belong to a planar structure, which increases the difficulty of integration and processing, and is not easy to promote and use.

Abstract

The invention discloses a single-spiral slot antenna based on coplanar waveguide feed. The single-spiral slot antenna comprises a dielectric-slab with one side coated with copper and a slot antenna etched thereon, wherein the slot antenna comprises a coplanar waveguide feed line and two open loop resonators loaded with single-spiral line structures; the coplanar waveguide feed line is composed oftwo signal transmission slots, an intermediate conduction band and a metal ground; and the two open loop resonators loaded with single-spiral line structures are symmetrically arranged on two sides ofthe coplanar waveguide feed line, and separately connected with the signal transmission slots via slot line sections. The antenna is compact in size, simple in structure, low in profile, convenient to machine, low in cost and prone to being integrated with other microwave circuits. The antenna can well cover 5.2 / 5.5 / 5.8GHz of WLAN and WMAIX, and the working frequency and performance of the antenna can be effectively adjusted through adjusting the sizes of different design models.

Description

technical field [0001] The invention relates to the technical field of microwave communication, in particular to a single helical slot antenna fed by a coplanar waveguide. Background technique [0002] In 1887, after the German scientist Hertz verified the existence of electromagnetic waves through experiments, human beings entered the era of developing and using electromagnetic waves. Wireless communication is developing rapidly in social work and life, and wireless application equipment is also increasing day by day, and antenna, as an indispensable part of wireless communication system, has also received more and more attention from researchers. In the 21st century, with the continuous advancement of wireless technology, indoor wireless networks and global microwave interconnection access are gradually popularized, and antennas working on WLAN (wireless local area network) and WIMAX (global microwave interconnection access) are increasingly popular. The slot antenna fed ...
