What Is The Condition On Phase For The End Fire Array With Increased Directivity? |
|
Answer» When δ = - β d, produces maximum field in the direction φ = 0 but DIES not give the maximum directivity. It has been shown by Hansen and woodyard that a LARGE directivity is obtained by INCREASING the PHASE change between the sources so that δ = - (βd + π / n ). This condition will be referred to as the condition for increased directivity. When δ = - β d, produces maximum field in the direction φ = 0 but dies not give the maximum directivity.
