✦ Synopsis
An X-band four-element linear microstrip leaky-wa¨e ( ) antenna LWA array with a dual-beam radiation pattern and twodimensional scanning capability is de¨eloped. The measured halfpower beamwidths of the H-plane and quasi-E-plane radiation patterns are less than 30Њ. By tuning the dc bias of the ¨aractor phase shifter between the antenna elements, the main beam can be scanned in the azimuth plane from y13Њ to q13Њ off broadside. In the ele¨ation plane, the beam-scanning angle is close to 20Њ as the operating frequency is tuned from 11.58 to 12.5 GHz.
