A Study on a Method for Measuring Broadband Permittivity of Molding Compounds through Multiplication-Dependent Current Distribution Analysis of Ring Resonators
링 공진기의 체배종속적 전류분포 해석을 통한 Molding Compound의 광대역 유전율 측정 방법 연구

In this study, we propose an algorithm that complements the frequency dependence of the relative permittivity conversion equation applied for the measurement of relative permittivity through a ring resonator. The broadband electrical characteristics of an epoxy molding compound (EMC) used in the fan-out wafer-level packaging (FOWLP) process were measured using our algorithm. By proposing a formula for calculating the permittivity that reflects the current distribution at the multiplied frequency of the microstrip ring resonator, the effective r...

Design of a Compact-Sized Broadband Lumped-Distributed Balun Including Impedance Matching
임피던스 매칭을 포함하는 소형 광대역 집중소자-분산 발룬의 설계

https://doi.org/10.5515/KJKIEES.2022.33.12.911

In this paper, the design of a compact broadband lumped-distributed balun, including impedance matching, is suggested. For the broadband impedance characteristic of the suggested balun design, the even-mode impedances of the balun were analyzed using the differential port impedance (Z_in). The proposed balun enables broadband impedance matching without an additional impedance-matching network, thereby reducing the circuit size and passive loss. The suggested balun was fabricated using FR4-based PCB and its performance...

From after the sinking of the Sewol ferry in 2014, ship accidents such as the sinking of small fishing boats have continued, leading to casualties. If the information delivery system is strengthened during the maritime search and rescue process after a ship accident, the loss of life will be reduced. The first way to strengthen maritime search and rescue information delivery systems is to use drones. When using drones, the search video can be shared in real time, and command-and-rescue operations can be effective. The second is the placement of...

This study utilized the clustering-based CBF(characteristic basis function) generation algorithm to reduce the computing time of CBFM(characteristic basis function method), which is an accelerated version of moment methods in electromagnetics. As an efficient optimization of block generation, the meshes are grouped using the clustering algorithm, resulting in a reduction in the CBF computing time. In this study, we optimized the mesh distribution using the K-means clustering algorithm and verified the performance of the clustering-based method....

https://doi.org/10.5515/KJKIEES.2022.33.12.931

Two types of transmission resonances are investigated with main interest centering on the transmission resonance condition. One is the transmission resonance through the Bethe’s small hole in the waveguide screen. The other is the transmission resonance through the 2D planar square array of the Bethe’s small holes. As a common feature between two structures, Rayleigh type Wood’s anomaly is observed to be associated with the transmission resonance phenomena for the two cases. In particular, the physical reason for the transmission resonanc...

Adaptive Beam Scheduling Algorithm Considering Changes in the Posture and Position of Airborne Radar
항공기탑재 레이다의 자세와 위치 변화를 고려한 적응적인 동시운용모드 빔 스케줄링 기법

Jeongjik Seo, Yongjun Hong 서정직, 홍용준

https://doi.org/10.5515/KJKIEES.2022.33.12.939

The purpose of an interleaved mode is to simultaneously provide two or more modes to the user. For this, the time resources allocated to each mode are reduced, and thus, the performance of each mode is degraded. Therefore, a scheduling method is required that can minimize the performance degradation of each mode by appropriately allocating resources. In the interleaved mode that operates the ground imaging and air-to-air search/track modes, the image update interval is longer than that of the single mode operation, and air-to-air tracking perfo...

Development of LDA Based Hand Gesture Classification Algorithm Using Distributed Radar System
LDA 기반 분산 레이다 시스템을 활용한 손동작 분류 알고리즘 개발 및 성능 분석

https://doi.org/10.5515/KJKIEES.2022.33.12.948

In this study, we propose a linear discriminant analysis (LDA)-based classification algorithm for distributed radars that share their data at a data fusion center over wireless channels. Instead of sharing high-dimensional micro-Doppler signature (MDS) data over the resource-limited backhaul, each radar applies the LDA algorithm to reduce the dimension of the data. Because the dimension-reduced MDS data is a vector with complex values, it is expressed as a real-valued probability vector using the softmax processing method to reduce the quantiza...

A Study of Motion Compensation for Electronic Beam on Sea Environments
해상 환경에 따른 전자빔 보상방법 연구

Juho Yun, Ji Woong Paik, Jongil Park, Kichul Yoon, Kwan Sung Kim 윤주호, 백지웅, 박종일, 윤기철, 김관성

J. Korean Inst. Electromagn. Eng. Sci. 2022;33(12):960-965.
https://doi.org/10.5515/KJKIEES.2022.33.12.960

In this study, motion compensation for electronic beams in sea environments is proposed. Because the radar on a ship fluctuates according to the sea environment, it is necessary to compensate for the fluctuation to achieve accurate beam steering. Unlike the fluctuations in the pitch and yaw directions, where only compensation for the beam steering value is required, the fluctuation in the roll direction causes the beam to rotate. Therefore, compensation for the rotation of the beam in the roll direction is necessary. For this purpose, beam rota...

This paper presents a 915 MHz low-loss harmonic transponder for harmonic radar sensors. The proposed through-type harmonic transponder comprises an input and output matching network with an independent impedance control circuit. This control circuit enables the independent matching of the input and output loads. The circuit minimizes the impedance influence between the input and output matching networks, regardless of the impedance change of the input and output terminals according to the internal and external environments. The designed harmoni...

https://doi.org/10.5515/KJKIEES.2022.33.12.970

In this study, an electrically small 3-stage monocone antenna with wideband characteristics is proposed. The proposed antenna consists of a 3-stage monocone radiator, a circular disk located above the radiator, shorting pins connecting the circular disk and the ground plane, and parasitic structures. The impedance matching characteristics in the high-frequency band are improved by dividing the monocone radiator into three stages. The insertion of a slot in the circular disk improves the mid-frequency band performance. The low-frequency band is ...
