Design of Miniaturized Broadband Butler Matrix for 5G Beamforming System
5G 빔포밍 시스템을 위한 광대역 버틀러 매트릭스 소형화 설계

Jin-yeong Jung, Byung-Sung Kim 정진영, 김병성

https://doi.org/10.5515/KJKIEES.2023.34.8.591

This paper proposes a compact 4 × 4 Butler matrix (BM) with broadband characteristics within the 5G NR frequency range (3 GHz ~4.5 GHz). To achieve broadband performance, 3 dB broad-side coupler with optimal parameters was implemented, and the circuit was designed with a strip line based on the FR-4 four-layer structure to reduce the size. The average implementation loss was measured as −1.5 dB, and the reflection coefficient was measured as over 15 dB across the entire frequency range. Phase differences of −45°, 135°, −135°, and 45�...

Analysis on the Effect of Spurious Signals of Transmission and Local Oscillation Signals in a Compact Radar
소형 레이다에서 송신 및 국부발진신호의 불요파 영향성 검토

Mihui Seo, Jinsung Park, Hyunju Kim 서미희, 박진성, 김현주

https://doi.org/10.5515/KJKIEES.2023.34.8.599

The spurious signals of the transmission signal (FTX) and local oscillation signal (FLO) for a receiver are the factors that reduce the SNR(signal-to-noise ratio) performance of a radar. In particular, a spurious signal with a high-power level causes the radar to falsely indicate a target. However, the spurious emissions of a frequency synthesizer are unavoidable because of the nonlinearity of the RF active elements on the FTX and FLO paths. In this study, spurious requirements are provided to ensure the SNR performance of a compact radar. Cons...

This study develops a 600-GHz band array detector in a 65-nm CMOS technology. The unit pixel detector is based on a common-gate differential pair integrated with an on-chip differential patch antenna. A detector array was completed by arranging 36 pixels in a 6×6 configuration and integrating switches for row/column selection and signal path. The array exhibited average responsivity and NEP (noise equivalent power) of 1,320 V/W and 114 pW/Hz^0.5, respectively. Imaging experiments were conducted at approximately 600 GHz by utilizing...

To apply active electronically scanned array (AESA) radars to aircraft, such as light attack aircraft, unmanned aerial vehicles, and drones, a radar system designed with a compact and lightweight AESA antenna device and an air-cooled heat dissipation structure is required. This paper presents the design and fabrication results of the first domestic X-band air-cooled, compact, and lightweight active phased array antenna device for aircraft. To dissipate heat from the AESA antenna unit by air cooling, a heat dissipation fin was applied to the tra...

Design and Fabrication of N-Way Calibration Line for Active Electronically Scanned Array Radar
능동 전자주사식 위상배열 레이다용 N-Way 보정선로 설계 및 제작

In this study, we describe the design and fabrication of an N-way calibration line for an active electronically scanned array radar. The designed calibration line consisted of an open-ended probe and a Wilkinson power divider. It was designed to calibrate by measuring the amplitude and phase of the transmit/receive path. In addition, the signals from the array antenna and transmit/receive module could be transmitted to a calibration assembly using the open-ended probe and power divider. A multilayer printed circuit board (PCB) was used for mini...

Load-Based Beam Operating Algorithm Design and Analysis of Test Results for the AESA Radar Interleaved Mode
AESA 레이다 동시 운용 모드 부하 기반 빔 운용 알고리즘 설계 및 시험 결과 분석

Jin-Ju Won 원진주

J. Korean Inst. Electromagn. Eng. Sci. 2023;34(8):638-646.
https://doi.org/10.5515/KJKIEES.2022.34.8.638

The interleaved mode has the effect of operating multiple modes simultaneously by operating two or more single modes in a time division using the agile beam steering capability of the AESA(active electronically scanned array) radar. During the air-to-ground/sea mode operation, the air-to-air mode is simultaneously operated for quick recognition and response to air threat targets. In this study, the processing unit was set differently according to the mode for an efficient interleaved mode. It is the design of the load-based beam operating algor...

Circular Mean of Scatterers’ Angles as the Mode of Angle Estimates with Monopulse Radar
모노펄스 레이다 추정각도의 최빈값과 산란점들 각도의 원형 평균과의 관계

Joohwan Chun, Junyoung Jung, Jongchan Woo, Sangwoo Park 전주환, 정준영, 우종찬, 박상우

J. Korean Inst. Electromagn. Eng. Sci. 2023;34(8):647-650.
https://doi.org/10.5515/KJKIEES.2023.34.8.647

In radar, an extended target or structure is perceived as a collection of multiple point scatterers. For tracking radar, determining the weighted mean (or centroid) angle of these unresolved scatterers is crucial. Our study demonstrates that the monopulse angle estimate corresponds to the weighted circular mean of the angles of multiple scatterers, as supported by both analytical and simulation results.
