Abstract

Антенна (10), которая может быть использована в мобильном телефоне или другом аналогичном устройстве связи, имеет передающий элемент (21) для передачи и приема направленного электромагнитного излучения. Передающий элемент (21) выполнен на слое или слоях (25) диэлектрика, причем ориентация диаграммы направленности принимаемого или передаваемого излучения управляется с помощью электронных средств. Передающий элемент (21) включает в себя по меньшей мере одну петлю и, как правило, имеет форму спирали. Переключатели (23, 24) в виде микроэлектромеханического переключателя или p-i-n-диода, обеспечивающего возможность короткого замыкания или размыкания цепи элемента (21), позволяют изменять ориентацию диаграммы направленности излучения. Диэлектрическая проницаемость диэлектрика (25) является переменной, что также оказывает влияние на ориентацию.
