Antenna Builder

Motivation

The aim of this tool is to give user-controlled graphical interface where it is possible to draw a planar antenna structure and the program returns current/charge distribution and evaluates one of pre-defined task.

Tasks

Minimize Q-factor of antenna

The computed Q-factor value invites to find an antenna which minimizes this important antenna metric. As an option, a genetic algorithm can be employed for this minimization process.

Maximize received power

Design an antenna which maximize received power from plane wave that perpendicularly incident the antenna body.

Distribution

Antenna Builder download is freely available. The tool needs AToM package to operate (at least its free version). An option using genetic algorithm also requires FOPS package.

EMiT 2018

On February 27, 2018, Department of Electromagnetic Field at CTU FEE Prague organized a student workshop entitled Electromagnetic Tuesday (EMiT), where students could see the actual research topic in applied electromagnetism. The Antenna Builder was one of the interactive shows.

At the end of the workshop, Antenna Builder application registered 20 users and 1222 antenna designs. Best solutions for each user are shown in the following table. Three best designs have been awarded a prize.

EMiT 2019

The second year of EMiT was held by Department of Electromagnetic Field at CTU FEE Prague on February 26, 2019. The Antenna Bulder was part of interactive workshop again - this year with the task to maximize the received power.

Into Antenna Builder application was registered 23 users (21 visitors and 2 authors of AB) who created 2233 antenna designs. Best solutions for each user are shown in the following table.
