This paper presents a new technique to improve the performance of a 2.5 GHz low-temperature co-fired ceramic(LTCC) miniaturized bandpass filter(BPF) with four transmission zeros. The BPF, which is composed of parallel coupled lines with end-shorted line and lumped capacitors, has vertically stacked coupled lines for realizing multiple transmission zeros. The compact LTCC filter has one of the smallest reported footprints(2×1.25×0.75 mm²) and demonstrates the highest roll-off factor(24 dB / 100 MHz) in the 2.5 GHz band. The inserti...

We designed a lightweight, deployable reflector antenna for use in a small satellite SAR. The CFRP composite material was used for the deployable panel to reduce weight, and a deep reflector type antenna was designed by using a feeder with a large beam width to increase the storage efficiency of the antenna. The structure of the strut that can minimize the effect on the antenna performance was designed and placed in a suitable position to optimize the structure to support a feeder. The electrical performance of the manufactured reflector antenn...

This paper describes the design & fabrication and measurement results of a wide band(S to C band) 80 W solid state power amplifier(SSPA) using a GaN HEMT. The SSPA is fabricated with wide band impedance matching topology in a balanced combined configuration using two GaN HEMT bare dies and with a super CMC(S-CMC) structure with high thermal conductivity using the eutectic bonding carrier packaging method. The wide band 80 W SSPA, with 42 dBm CW input power injection at operation frequency, demonstrated performance with an average output pow...

Development of Pulse-Tracking Noise-Generation DRFM(Digital Radio Frequency Memory) Using Phase Synthesis
위상 합성을 이용한 펄스 추적 잡음발생 DRFM 개발

Sang-Su Kim, Jung Ho Kim, Sang-Wang Cho, Jae-Heon Ko, Jeil Jo 김상수, 김정호, 조상왕, 고재헌, 조제일

https://doi.org/10.5515/KJKIEES.2020.31.9.780

In electronic warfare, to protect allies from enemies, DRFM(digital radio frequency memory) is used to receive threat signals and generate various electronic interference signals to deceive them. The use of noise is an efficient interference method, which is less affected by radar receiver characteristics. It is generated mainly by noise-generating devices. As the signal form of a modern radar changes in real time, the conventional noise generation method has a limitation of interference in response to a change in the threat signal. In this pap...

Near Field Immunity Test Using L-Probe Fed Circular Patch Antenna to Simulate ISO 11452-2 Test Environment
L-Probe 원형 패치 안테나를 이용한 ISO 11452-2 근거리 내성 시험 모사에 대한 연구

Doo-Jin Lee, Jun-hee Han, Wan-Soo Nah 이두진, 한준희, 나완수

J. Korean Inst. Electromagn. Eng. Sci. 2020;31(9):788-798.
https://doi.org/10.5515/KJKIEES.2020.31.9.788

ISO 11452-2 is a well-known standard that tests the electromagnetic immunity of a device under test(DUT) in an anechoic chamber. ISO 11452-2 needs a large antenna and high-power amplifier to provide a high electric field in the chamber. In this test setup, finding the root cause and debugging issues is not easy because of varied limitation conditions. In this paper, we suggest two L-probe-fed circular patch antennas that emit a high electric field(over 800 V/m in the radar pulse ranges) on DUTs in the near field. Because the DUT is located 50 m...

In this paper, we propose a method for analyzing the nonlinear characteristics of a squint synthetic aperture radar(SAR) signal conversion process and estimate the system operating range suitable for stable SAR image reconstruction using the proposed method. The Doppler spectrum can be analyzed by applying the principle of stationary phase to the squint SAR signal model. Consequently, the relationship between the azimuth samples and the Doppler frequency can be derived. The nonlinear error of this relationship formula optimized for the squint S...

In this study, a wireless power transmission system supporting multiple users was built based on a power pilot. The power pilot transmits the authorization and power status information of the user to the power station. The power station first transmits power to the user in the lowest power state for the longest time. A code-division multiple access system was used for supporting multiple receiving users and a non-uniform time-division multiple access system, which allocates power charging time differently to each user, was employed. Consequentl...

Least-Squares Approach Using Moving-Averaged Signals for Transmit Power and Path Loss Exponent Estimations in Wireless Sensor Networks
이동평균과 최소자승을 이용한 무선 센서 네트워크에서 표적의 전송파워와 경로손실지수 추정

https://doi.org/10.5515/KJKIEES.2020.31.9.816

In this paper, we present an estimation scheme for the transmit power(TP) and path loss exponent(PLE) for hybrid target localization in wireless sensor networks. In the absence of knowledge on the TP and PLE, hybrid target localization schemes that utilize both received signal strength (RSS) and angle of arrival(AOA) measurements have significantly reduced performances. To estimate the TP and PLE in the presence of a severe measurement noise, moving-averaged RSS measurements are applied to a least-squares algorithm utilizing a tentatively estim...

In this study, a method was proposed to develop a compact antenna for a drone-borne synthetic aperture radar(SAR). The compact antenna structure was designed as a microstrip patch antenna, and a parasitic patch was stacked on the radiation patch to improve the bandwidth and gain of the antenna. The size and interval between patches were iteratively adjusted based on the simulation in order to satisfy the requirements of the antenna. Additionally, HH-, VV-, HV-, and VH-polarimetric antennas were fabricated to acquire fully polarimetric SAR data....

https://doi.org/10.5515/KJKIEES.2020.31.9.827

In this study, an 8×8 patch array antenna for a 28-GHz-band 5G mobile communication small base station was designed and implemented. To increase the right-hand circular polarization axial ratio(AR) bandwidth, a 2×2 subarray element was set to a sequential feed. Measurement results for the implemented antenna on a polytetrafluoroethylene substrate show a frequency bandwidth of 2.02 GHz(7.246 %BW) based on a reflection coefficient of −10 dB. The measured AR at 0° was 2.71 dB, while the 3-dB AR bandwidth was 1.18 GHz(4.24 %BW). The gains of t...
