Performance Characteristics of a Squashed UWB Fractal Aerial for Weather Radar Systems

Abstract

In this proposal, a compacted octagonal- formed Ultra wide-band aerial along with fractal-shaped Minkowski notch and a twofold C- formed notch is offered. The projected antenna exhibits a four band frequencies operating at 3.9.GHz, 5.9.GHz, 7.9.GHz and 9.9.GHz. Furthermore, a rectangular aperture besides inserted the position plane, which helps to attain the required UWB bandwidth. The size of the planned structure is 27.1X16.6 𝑚𝑚^2, shows suitable matching of impedance, constant radiation pattern with superior directivity over the entire UWB frequency range. The planned structure can be used for UWB Applications such as satellite (3.7 to 4.2 GHz) and weather radar systems. This frequency band is also used in civil and military applications for maritime navigation radar systems.
