Receiver for Jupiter


Broadside Case

In this the power o/p from the two dipoles are added in phase in power combiner. The half wavelength section is used in between the dipole and power combiner. The half wavelength transmission line has property that its i/p impedance is the same as the load impedance connected to its other end. The o/p of power combiner is brought to receiver using a coaxial cable, one wavelength long. Since the power from two dipoles is added in phase, we get the antenna beam looking up towards Zenith. i.e. broadside which means direction of radiation is perpendicular axis of array and also to plane containing the array elements.
(In actual practice I am using 1.5-wavelength cable from each dipole to power combiner. And 2-wavelength cable from power combiner o/p to receiver.)
