Özet
This paper introduces a novel reconfigurable microstrip antenna designed for satellite communication applications, capable of operating across the S (2–4 GHz), C (4–8 GHz), and X (8–12 GHz) bands. The proposed antenna dynamically adjusts its frequency, polarization, and radiation pattern, offering 16 reconfiguration modes across 14 distinct resonance frequencies. These resonance frequencies are non-overlapping and are realized through manual control of the diode biasing states, enabling the antenna to switch between predefined modes, each characterized by a distinct frequency response. Constructed using Rogers RT/duroid 5880 with dimensions of 28.4 × 30 × 0.508 mm3, the antenna integrates a custom-designed control circuit, developed in Altium and analyzed with ADS, to govern the operation of four RF PIN diodes for rapid reconfiguration. The design process employed advanced simulations using CST and HFSS and optimization techniques to maximize gain, directivity, and efficiency. Empirical measurements corroborate the simulation results, demonstrating a maximum gain of 6.34 dBi and a peak efficiency of 98%. The antenna’s compact size, combined with its enhanced gain, directivity, and efficiency, represents a notable improvement over existing designs. This research demonstrates substantial improvements over existing reconfigurable antenna technologies by offering a versatile and high-performance solution suitable for next-generation satellite communication and radar systems. The proposed design introduces enhanced operational capabilities that may serve as a reference point for future antenna development efforts.
