Abstract:
A hybrid corrugated horn for dual band operation at a selected frequency band wherein a window at one end of the band is provided for transmitting information and a window at a second end of the band is provided for receiving information, the horn comprising the following elements considered in combination with one another:a throat segment including circular corrugations that increase linearly in pitch for frequency matching within the transmit and receive windows of the selected band and for input impedance match; a middle segment including two conical sub-sections of dual-depth circular corrugations wherein a first conical sub-section flares up in angle and a second conical sub-section flares down in angle to optimize sending and receiving of information within the transmitting and receiving windows of the selected band; and a final segment including a smooth-wall, truncated circular cone section having a minor circumference and area for mating with the circumference and area of a last groove of the second flared section of the middle segment of the horn and a major circumference and area that matches the circumference and area of a last web within the horn for radiating modulated energy into space and for receiving modulated energy from space to interchange information.
