In this paper, we present a phase-corrected horn antenna with improved directivity. An increase in the horn aperture size results in a significantly non-uniform phase distribution contributing to the poor radiation characteristics. A low-profile phase correction surface (PCS) is therefore designed to address this problem. Significant improvement has been achieved in the horn antenna performance by placing the proposed PCS right at the mouth of the horn. The near-field transformation method is applied to demonstrate an improvement of 10 dBi in the peak directivity at the operating frequency of 11 GHz. This feature can be extended to manipulate the far-field pattern of horn and even for beam steering applications.

Abstract

In this paper, we present a phase-corrected horn antenna with improved directivity. An increase in the horn aperture size results in a significantly non-uniform phase distribution contributing to the poor radiation characteristics. A low-profile phase correction surface (PCS) is therefore designed to address this problem. Significant improvement has been achieved in the horn antenna performance by placing the proposed PCS right at the mouth of the horn. The near-field transformation method is applied to demonstrate an improvement of 10 dBi in the peak directivity at the operating frequency of 11 GHz. This feature can be extended to manipulate the far-field pattern of horn and even for beam steering applications.
