In this paper, we present a power optimization solution based on the automatic power control method using a closed-loop algorithm for the uplink power control device (UPC) of the satellite communication HUB station. The results are evaluated by theoretical analysis and validated by simulation model on Matlab software, finally the model has also been used in the UPC device and tested in practice.

In this paper, I will deal with dual-band electrically small antenna (ESA). The miniaturized radiation structure consists of a small ring and concentric split-ring resonator. The resonant response of the proposed radiation structure is characterized by the coupling among two split-ring resonators and the small ring. This interaction provides an additional capacitance to further reduce the total dimension of the resonant electrical length.
