The fractal antennas are designed to be compact as well as multi-band use at UHF (ultra high frequency) and microwave frequencies. The first three iterations of the Koch snowflake were designed and simulated through COMSOL. Each antenna was designed for the UHF band and an analysis of the second band is given in the paper.
The dipole antenna is one of the most straightforward antenna configurations. It can be realized with two thin metallic rods that have a sinusoidal voltage difference applied between them. The length of the rods is chosen such that they are quarter wavelength elements at the operating frequency. Nov 18, 2016 · Tutorial 4 - Simple Dipole Using Comsol Multiphysics 5.2. This is a tutorial for COMSOL 5.2. It demonstrates a simple example of how to create and simulate an electric dipole in air. The plotted ... A large reflector can be modeled easily with the 2D axisymmetric formulation. In this model, the radius of the reflector is greater than 20 wavelengths and the reflector is illuminated by an axial feed circular horn antenna. The simulated far-field shows a high-gain sharp beam pattern
In order to optimize antenna directivity, it's important to first measure the effectiveness of the radome design. With the COMSOL Multiphysics® software, we have access to features and functionality that enable us to do just that. To illustrate this, let's look at the example of a patch antenna, which is popular in modern wireless devices.Symptoms of a worn clutch basketcdn.comsol.com
i am completely new to COMSOL and i am struggling with a few basic things for my uni project. I followed the tutorial for the inset microstrip antenna provided. I must have done this ten times now and it works fine. I tried to transfer the same procedures over to my design, a circular polarised microstrip antenna but i am having a few problems.About Comsol.

The microstrip patch antenna is used in a wide range of applications since it is easy to design and fabricate. The antenna is attractive due to its low-profile conformal design, relatively low cost and very narrow bandwidth.The radiation pattern of the antenna has been noticed by changing frequency 7.494811 MHz to 134.9066 MHz. The simulation work is made by using Matlab2018a and Comsol Multi-Physics simulation software.
