- What is an electromagnetic interference? What is source of disturbance?What is coupling path? What is is crosstalk? What is ground plane?design an ordinary end fire uniform linear array with only one maximum so that its directivity is 20 dB (above isotropic). The spacing between the elements is lambda/4 and its lenth is much greather than the spacing. Determine the (a) the number of elements (b) overall length of the array (in wavelengths) (c) approximate half-power beamwidth(in degrees) (d)amplitude level (compared to the maximum of the major lobe) of the first minor lobe (in dB) (e) progressive phase shift between the elements (in degrees)can you please check this? Thank you!
