摘要：
An innovative phaseshifterless, wideband, microstrip leaky-wave antenna with an electronically steerable dual-pencil-beam pattern in the H-plane is presented. The log-periodic geometry of the leaky slots of the antenna results in a wide bandwidth of 25.19%. The fan beam can be steered up to 14 degrees over the wide resonating band of the antenna. The beam is also steerable at a fixed frequency, by reactivelty loading the slots and a maximum steering angle of about 14 degrees is observed for different capacitor values with an improved bandwidth of 33.3%. This concept is studied using passive components, but it can be extended to varactors. (c) 2005 Wiley Periodicals, Inc.
