Patent ID: 7109928

Claim:
Leaky wave microstrip microwave radio frequency antenna apparatus comprising the combination of: a radio frequency energy conveying elongated electrical conductor received on a metal ground conductor backed planar electrical insulating substrate member; said planar electrical insulating substrate member exceeding said elongated electrical conductor in width by at least one half wavelength of said microwave radio frequency; an array of electrical shorting element conductors transversely disposed on said planar electrical insulating substrate member along a lengthwise axis of said elongated electrical conductor and connecting said radio frequency energy conveying elongated electrical conductor with said metal ground conductor backing of said planar electrical insulating member at a plurality of periodic intervals along said radio frequency energy emitting elongated electrical conductor; and a microwave electrical energy transmission line element connecting with an energy communication end node of said radio frequency energy conveying elongated electrical conductor and also connected with an antenna energy electrical apparatus.
