Abstract
A broadband quasi-Yagi X-Band antenna array with a fanbeam-pattern is presented. The bandwidth of the array (VSWR < 2.0) is found to be 50% and a measured gain of 10-12 dB is measured in the operating range. An array with a 12° beam tilt is also presented. The endfire array demonstrates a front-to-back ratio better than 20 dB and cross-polarization better than ¿15 dB in the operating band. The fanbeam pattern is useful for mobile communications applications. Active 2-D arrays based on this concept should prove useful for radar, communications and quasi-optical power combining applications.
