Pixelová elektricky malá anténa

Abstract

Bakalárska práca sa zaoberá problematikou naprogramovania a implementácie binárnych evolučných algoritmov a ich následným využitím pre návrh pixelovej elektricky malej antény pre ISM pásmo 868 MHz. Predstavené a implementované sú dva binárne evolučné algoritmy vytvorené v programovacom prostredí Matlab. Základný návrh a optimalizácia antény prebehla v programe CST, kontrolovaná Matlab kódom. V práci je empiricky skúmaná miniaturizácia elektrickej malej antény a jej citlivosť na okolité prostredie.This bachelor thesis deals with the problematic of programming and implementation of binary evolutionary algorithms and their practical application for design of pixelated electrically small antenna for ISM band 868 MHz. Two binary evolutionary algorithms are introduced and implemented, both created in the programming environment Matlab. The basic antenna design and its optimization are performed by the program CST controlled by an in-house Matlab code. In the thesis, an empiric research of miniaturization and sensitivity of the electrically small antenna is conducted.This bachelor thesis deals with the problematic of programming and implementation of binary evolutionary algorithms and their practical application for design of pixelated electrically small antenna for ISM band 868 MHz.
