| Abstract: | A new antenna structure consists of modified suspended substrate microstrip line with multilayer dielectric is proposed for getting desirable leaky characteristics. It is demonstrated that a suitable choice of the structure dimension can guarantee the antenna working in the antenna-mode region to make the antenna operate in an efficient way. Besides, very flat variation of the leakage constant with frequency can be achieved. It is a property for practical application as a frequency scanning antenna since it ensures a stable radiation pattern with little distortions while beam is being scanned. |
