Single antenna using two feed horns (one for receiving and radiation X-band signals, and one for S-band signals), in conjunction with ellipsoid reflector and dichronic plate, can accommodate two different frequencies simultaneously.
By superimposing two hybrid modes, backlobes of S-band gain calibration horn are down 70 to 80 dB.
It is shown that a transform-pair relationship exists between incident and scattered fields from an infinite, perfectly conducting reflector of arbitrary shape, when the physical optics approximation is applied. As an example of potential applications, this relationship is used to synthesize a reflector feed pattern required to produce a desired far-field pattern from a given paraboloidal reflector.
A dual frequency feed system for a Cassegrainian antenna is provided wherein two frequencies may be transmitted along a single boresight or received simultaneously using a single antenna.
