Five-element array. An antenna array is made of five Hertzian dipoles, spaced λ/4 apart and driven in phase. The dipoles are parallel to each other.
(a) Find the array radiation pattern of the antenna.
(b) What is the direction of maximum power?
1. What is the maximum number of homogeneous phases that can exist at equilibrium for a system involving
A frictionless piston cylinder device arrangement initially contains 8kg of saturated water mixture at 200 Degrees Celsius. Heat is supplied to the mixture till all the mixture is converted to saturated vapour at constant pressure. Determine the fina..
Determine the force Q at the jaw of the shear for the 400-N force applied with () = 30°. (Hint: Replace the 400-N force by a force and a couple at the center of the small gear. The absolute angular displacement of the gear must be carefully determ..
