A review paper on conical corrugated horn antenna

This paper presents the review on different types of corrugated waveguides and the antennas for far field radiation pattern. This kind of antennas having a better gain and directivity and the side lobe levels are comparatively low. The side lobe levels can be further reduced by the applying the concept of corrugation to the walls. The significant disadvantage of TE₁₁ mode, side lobes and cross-polarization, is reduced by the HE₁₁ mode. Now a days, working with a new type of corrugated horn antenna, consists on generating the fundamental Gaussian beam directly from the TE₁₁ mode. These antennas are used when high degree of symmetry in radiation field and low cross polarization with high gain and pencil beam is required. This kind of Gaussian profile horn antenna having lower aperture in size.
