This paper presents a reconfigurable reflectarray antenna (RRA) that uses a metasurface to achieve circular polarization-switching capability. A method for switching to right-handed circular polarization (RHCP) or left-handed circular polarization (LHCP) by setting the reference phases of the x- and y-polarized unit cells as in-phase or out-of-phase is proposed. In addition, an optimization method for improving the axial ratio by shifting the reference phases of the two orthogonal polarizations is presented. Si...

In this study, a circularly polarized antenna-in-package array antenna with an expandable axial ratio bandwidth was proposed using a rotating sequential feed structure. Each antenna in the proposed design had a hexagonal shape for a triangular array configuration and featured a circular radiating patch. In addition, it was fed by two pins through a feed line with a 90° phase difference to implement circular polarization characteristics. A 2×2 subarray antenna was designed to enhance the axial ratio bandwidth by rotating each antenna by 90° a...

J. Korean Inst. Electromagn. Eng. Sci. 2024;35(3):200-204.
https://doi.org/10.5515/KJKIEES.2024.35.3.200

This study presents an 8~15 GHz low noise amplifier (LNA) using a 0.25 μm GaN on SiC process. The LNA is designed in three stages with source degeneration in the first stage to optimize the noise figure and operation bandwidth. Lossy matching using a resistor is applied to the drain nodes in each stage to enhance stability. An RC parallel equalizer is applied to the output port to flatten the frequency response. The chip size of the fabricated LNA MMIC is 3.0 mm×0.9 mm. At operating frequencies of 8~15 GHz, the small signal ...

Design of High-Efficiency and High-Power Inverse Class-F GaN HEMT Synchronous Rectifier
고효율 고전력 Inverse Class-F GaN HEMT 동기 정류기 설계

Yusung Na, Nguyen Dang An, Chulhun Seo 나유성, 응웬당안, 서철헌

J. Korean Inst. Electromagn. Eng. Sci. 2024;35(3):205-210.
https://doi.org/10.5515/KJKIEES.2024.35.3.205

In this study, a high-efficiency, high-power synchronous rectifier based on transistors was designed. The widely used diode-based rectifiers have a relatively simple structure but are unsuitable for high-power applications, such as unmanned aerial vehicle and electric vehicle charging. In contrast, transistor-based rectifiers operate by reversing the power flow of a switch-mode power amplifier from the load to the DC supply based on time-reversal duality and can rectify efficiently, even at a high power of 30 dBm or more. The proposed transisto...

Interconversion of Voltage, Current, and Power Sources in Electromagnetic Simulation
EM 시뮬레이션 시 사용되는 전압/전류/전력원의 상호 변환에 대한 연구

Hyunjae Lee, Junhee Han, Gyeong-Ryun Choi, Wansoo Nah 이현재, 한준희, 최경륜, 나완수

J. Korean Inst. Electromagn. Eng. Sci. 2024;35(3):211-223.
https://doi.org/10.5515/KJKIEES.2024.35.3.211

This study developed a method for interconverting voltage, current, and power sources used in electromagnetic (EM) simulations. By incorporating voltage and current waves, equations for power, voltage, and current were derived while accounting for the presence or absence of transmission lines between the source and load. In particular, in the absence of a transmission line between the source and load, the characteristic impedance of the transmission line appears in these equations. To elucidate this observation, the equations for voltage, curre...

Comparative Analysis of Scattering by Impedance and Dielectric Objects Computed by Integral Equation- and Reflection-Based Iterative Physical Optics Algorithms
적분방정식과 반사계수를 기반한 두 Iterative Physical Optics의 임피던스 및 유전체 물체 산란 해석 비교

https://doi.org/10.5515/KJKIEES.2024.35.3.224

Given their high analytical speed, iterative physical optics (IPO) algorithms present an advantageous approximation method for analyzing the electromagnetic scattering of electrically large objects. IPO approaches for radar cross-section (RCS) prediction are of two types-one based on integral equations, and the other based on reflection coefficients. Integral equation (IE)-based IPO approaches have remarkably low computational complexity and facilitates the analyses of conducting and impedance media. In contrast, reflection (R)-based IPO approa...

This paper presents a signal generation architecture for simulating arbitrarily intercepted low-probability-of-intercept (LPI) signals in a battlefield environment. Additionally, the performances of deep learning models in classifying the generated signals are compared in terms of the classification time, GPU memory usage, and accuracy. Previous studies have utilized ensemble learning to minimize signal classification time and enhance accuracy; however, an explicit criteria for the adoption of deep learning models have been lacking.

Design of a Fast Chirp PLL Using Digital Phase Interpolator
디지털 위상 보간기를 이용한 고속 첩 PLL 설계

Jin-Uk Shin, Se-Jun Park, Jun-Ho Moon, Byung-Sung Kim 신진욱, 박세준, 문준호, 김병성

J. Korean Inst. Electromagn. Eng. Sci. 2024;35(3):239-244.
https://doi.org/10.5515/KJKIEES.2024.35.3.239

This study proposes a phase-locked loop using a two-point modulation technique for fast chirp generation. The frequency synthesizer consists of high- and low-pass regions. In the high-pass region, continuous frequency modulation was achieved using a charge digital-to-analog converter, while a self-calibration block compensates for the nonlinearity of the voltage-controlled oscillator. In the low-pass region, the synthesizer is locked to the desired frequency with a low spurious level using a divider, delta-sigma modulator, and digital phase int...

Analytic Comparison of Reflection-based and Transmission-based Absorptances for Planar Materials
평판형 소재에 대한 반사기반과 투과기반 흡수율의 해석적인 비교

Hyun Ho Park, Jong Hwa Kwon, Chang Hee Hyoung 박현호, 권종화, 형창희

J. Korean Inst. Electromagn. Eng. Sci. 2024;35(3):245-248.
https://doi.org/10.5515/KJKIEES.2024.35.3.245

In this study, reflection-based and transmission-based absorptances of normally incident electromagnetic waves for planar materials were theoretically derived. The reflectance, transmittance, and absorptance of dielectric and magnetic absorbing materials were then compared using analytical equations. In the case of dielectric absorbers, the difference between the reflection-based and transmission-based absorptances is more pronounced at lower frequencies; this persists across several gigahertz. However, as regards magnetic absorbers, the differ...

https://doi.org/10.5515/KJKIEES.2024.35.3.253

This study entailed the development of a complementary metal–oxide–semiconductor (CMOS) ultra-wideband (UWB) pulse generator with an inherent binary phase-shift keying (BPSK) modulation technique. The BPSK modulation technique in a pulsed oscillator has been proposed by the author in previous studies on K-band application. In this study, a W-band CMOS UWB pulse generator was developed using this technique. The W-band UWB pulse generator was implemented on a 0.13-μm CMOS chip with an active area of 0.08 mm². The output spectrum...
