Comparative Analysis of Various Adaptive Smart Antenna Techniques for Patch Array Feed Parabolic Antenna

The design of a patch antenna array feed for high frequency applications is the subject of this study. To improve directivity and radiation properties, the proposed array feed is fed to the parabolic reflector. Various adaptive beamforming approaches like linear adaptive beamforming algorithm like Least Mean Square (LMS), Recursive Least Square (RLS), Data reusing least mean square (DRLMS) and Decision feedback least mean square (DFE-LMS) are applied and compared over the patch array feed to evaluate the performance. It's also been used to cancel out interference in the appropriate direction. For C-band applications such as satellite communication, the design is presented as an alternate feed antenna to the traditional horn-based feed network. An 8x1 circular patch antenna array framework with a broadside radiation pattern is used in the suggested design. The F/D ratio of the parabolic reflector fed by the array is 0.36, equal to 1400 aperture illumination. Simulation analysis is used to verify the effectiveness of the suggested design and compare the performance of various adaptive algorithms.
