Radiation patterns of the proposed horn antennas at the frequencies of 30, 32, 34, 36, 38 and 40 GHz. Webexponential horn geometry where both have the same tuning frequencies. This last statement is an important definition that will be assumed throughout the remainder of this document. The resulting motion of the driver’s cone, the driver’s volume velocity, is amplified by the horn to become an even greater volume velocity at the horn’s mouth.
