| Popis: | This work investigates and develops the physical reconfiguration and deployment of a previously designed 2×2 corporate-fed microstrip patch antenna array. The physical reconfiguration of the antenna is achieved using a Miura-ori fold pattern due to its utilization for deployment. Increasing the fold angle impacts the input impedance and beamforming capabilities by changing the element spacing and orientation. The previous design experienced a graceful degradation in electromagnetic performance as the fold angle increased. Further optimization led to a more robust and functional antenna array system. The antenna is enhanced by designing the array with circularly polarized patch elements. The use of circular polarization eliminates the need to study the polarization changes during intermediate folding states and enables pattern reconfigurability. The performance of the circularly polarized array is evaluated over a comprehensive range of angles to evaluate the impact of physical reconfiguration. Results from a simulated circularly polarized array are provided for a 3GHz design. |
