Radiating Array 



The SAMB antenna is one side of a proposed four-sided configuration, each 

 side a planar array which scans ±45° from broadside in azimuth to give 360° cov- 

 erage. It consists of 32 elements in the horizontal plane and two elements in the 

 vertical plane. The radiating elements are of the logarithmic trapezoidal-tooth 

 (LTT) type and have been widely investigated. Figure 2 shows a portion of the 

 array with the elements. The ±45° scan sector is covered by from 28 to 32 discrete 

 beams which can be scanned sequentially or by jump-scanning with a high beam 

 agility. The average beamwidth is on the order of 5° in azimuth and 35° 

 in elevation.
