A dual ridge horn antenna operating in frequency range of 4-17GHz is designed using equation based exponential tapered part varies the impedance of the guide from 50 at the feeding point (double-ridged rectangular waveguide) to 377 at the aperture of then antenna. Designed horn antenna has a total length of 43.375mm which means it is very small in size and weight. An N-type coaxial line to rectangular double-ridged waveguide transition is introduced for coaxial feeding of the designed antenna. Major modifications are imposed on back cavity, exponential taper and to design antenna as small as possible.
