Concentric ring microstrip antenna
Abstract
A concentric ring element has been investigated as a dual frequency band microstrip antenna. A model is presented for calculating the input impedance properties that include mutual coupling effects. It is shown that the radiation patterns may be computed from the TM(12) mode fields for a single ring.
