✦ Synopsis

A frequency-scanning leaky-wa¨e antenna with an aperture-coupled feeding structure is presented. The aperture-fed structure is used to excite the microstrip first higher mode. In order to suppress the dominant mode, we add a sequence of co¨ered wire in the center of this antenna. The measured H-plane main beam is a pencil beam, and is continuously scanned 12Њ as the frequency ¨aries from 9.85 to 10.27 GHz. This feeding structure is ¨ery suitable for acti¨e phase antenna array applications.
