Фрактальные рамочные антенны на основе кривой ÐšÐ¾Ñ Ð°

Abstract

Ð’ данной выпускной работе исследованы фрактальные рамочные антенны на основе кривой ÐšÐ¾Ñ Ð° с целью определения Ñ‡Ð°ÑÑ‚Ð¾Ñ‚Ð½Ñ‹Ñ Ð´Ð¸Ð°Ð¿Ð°Ð·Ð¾Ð½Ð¾Ð², в ÐºÐ¾Ñ‚Ð¾Ñ€Ñ‹Ñ ÑÑ‚Ð¸ антенны являются широкополосными. При выполнении работы промоделированы первые три итерации фрактальной рамочной антенны на основе кривой ÐšÐ¾Ñ Ð° в программе MMANA-GAL и получены зависимости КСВ от частоты. Далее изготовлены эти же антенны из медной проволоки, и измерены экспериментально Ð¸Ñ ÐšÐ¡Ð’. Проведено сравнение Ñ€Ð°ÑÑ‡Ñ‘Ñ‚Ð½Ñ‹Ñ Ð¸ ÑÐºÑÐ¿ÐµÑ€Ð¸Ð¼ÐµÐ½Ñ‚Ð°Ð»ÑŒÐ½Ñ‹Ñ Ñ€ÐµÐ·ÑƒÐ»ÑŒÑ‚Ð°Ñ‚Ð¾Ð². Кроме того, рассмотрен ряд модификаций второй итерации антенны с целью увеличения широкополосности антенны при помощи создания Ð´Ð¾Ð¿Ð¾Ð»Ð½Ð¸Ñ‚ÐµÐ»ÑŒÐ½Ñ‹Ñ ÐºÐ¾Ð½Ñ‚ÑƒÑ€Ð¾Ð² для протекания тока.
