This study aimed to improve the power efficiency and complexity of an RF beamforming system transmitter operating indoors using a biasing control technique for each group. The group-by-group biasing technique applies both dynamic and group biasing techniques simultaneously. Using the dynamic biasing technique, an appropriate bias was applied to the output of the RF power amplifier for each channel to power the power amplifier in the low-power section. The efficiency was improved, and the system complexity that occurred when applying the dynamic...

The space-borne SAR (synthetic aperture radar) payload orbits the earth and can obtain SAR image data without any time and space constraints. Because of these advantages, the development of space-borne SAR has begun in Korea since the 2000s, and the demand for development is increasing further. Until recently, medium and large satellites developed in Korea were active SAR systems operated by electrical beam steering. However, if images should be acquired quickly within a limited time for a region of interest, a passive antenna SAR system is mor...

This study used a resonator based on an interdigital capacitor (IDC) to detect variations in the S-parameter with the concentrations of sodium chloride and glucose solutions in the microwave frequency range. The resonance frequency was selected by considering factors such as the resonator size and variations in the dielectric constant of water with temperature. A fluidic channel was positioned at the location with the strongest electric field distribution in the resonator, and simulations and measurements were conducted. The co...

This study proposes a design method for implementing a low-pass filter that suppresses harmonic components in an ultrawide bandwidth using a stepped impedance structure with a defected ground stripline structure. The proposed defected ground stripline structure can obtain an impedance ratio that is more than 60 times higher than those of other transmission lines and conventional defected ground structures, owing to the asymmetrical ground plane of the stripline, making it possible to design a stepped impedance filter with a wideband harmonic su...

https://doi.org/10.5515/KJKIEES.2023.34.10.768

Binary polar codes proposed by Arikan are the first error correcting codes that can achieve channel capacity in binary input discrete memoryless channels. However, the binary polar codes has a disadvantage in that the encoding and decoding latency are relatively high. Therefore, research has been conducted on non-binary polar codes to determine a solution for this. However, research on frozen symbols selection methods for constructing non-binary polar codes is currently rather insignificant. In this study, we propose a new frozen symbols select...
