MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202641073108 A) filed by Dayananda Sagar College Of Engineering on June 12, 2026, for A High-Gain Rectangular Microstrip Patch Antenna Array System For Ku-Band Satellite Downlink Communication In Low Earth Orbit Applications.
Inventors include Dr. Pushpa B R; Dr. Devaraju Ramakrishna; and Chaithra S.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: The present invention relates to a compact and high-performance rectangular microstrip patch antenna (MPA) array designed for Ku-band satellite downlink communication systems. The invention comprises a single rectangular patch antenna fabricated on a low-loss Rogers RT/Duroid 5880 substrate and an optimized planar array architecture capable of enhancing gain, radiation efficiency, and directional performance. The antenna operates at approximately 12 GHz and employs an inset microstrip feed mechanism for impedance matching. The invention further integrates a corporate feed network and optimized inter-element spacing to minimize mutual coupling while maximizing beam directivity. Experimental and simulation validations demonstrate superior return loss, low VSWR, high radiation efficiency, and enhanced gain suitable for LEO satellite communication terminals. The invention provides a lightweight, low-profile, cost-effective, and manufacturable antenna solution for next-generation satellite communication systems.
