ABSTRACT q=0 pQ1>  
The paper presents the results of investigations of 8pe0$r`b  
array antennas intended to radiate high-power pulses nQLs<]h1  
of nanosecond and subnanosecond length. The array X47!E |*  
element is a combined antenna optimized for a given (!</%^ZI  
length of the exciting voltage pulse. Linear array d*-Xuv  
antennas were investigated by the radiation wave }76.6=~
