Miniaturization of asymmetrical gaussian profiled corrugated horn

Abstract

In this paper, miniaturization of the asymmetrical profiled corrugated horn with low sidelobes, low cross-polarization, and good beam symmetry is presented. The miniaturized corrugated horn is designed at 2.48 GHz and optimizes the result between the frequency sweeps of 2 GHz to 4 GHz. At design frequency, the result of the S11 Parameter is -30.2966 dB, and the S11 Parameter remains below -20 dB between 2 GHz to 4 GHz. The asymmetrical profiled corrugated horn comprises the Gaussian Profiled Corrugation part and the most widely used Variable Depth Slot Mode Converter. The purpose of the mode converter is to generate hybrid mode in the corrugated horn antenna. The length of the asymmetrical profiled corrugated horn antenna after applying the miniaturization technique is only 3.5λ long. The designed horn full-fill the number of S-Band applications such as Satellite communication, Radio astronomy, Weather Radar, Surface ship radar.

Miniaturization of Microstrip Antenna Using Techniques of Meandering, Loading, and Bending Slots

“…The applications of microstrip antennas are wide and in many diversified fields such as microwave systems (2), tumor detection (3), cancer detection (4) and radio relay applications (5), etc. Simultaneously, as an important part of mobile terminal equipment, the design of antennas is also developing in the direction of miniaturization (6), low-loss (7), and multi-function (8). One of the existing challenges while realizing miniaturization of the antenna while ensuring that the performance of the antenna without any negative effect has become the main focus of many researchers and pose challenges towards microstrip antenna research.…”
