In general, a direction finding system based on array antennas is implemented using a digital beamforming method with the same number of receivers as antennas, or using an RF beamforming method where a single receiver has a plurality of phase shifters. However, both approaches require complicated hardware configurations, which is a major disadvantage. In this paper, we propose a new method to generate 4-beam patterns using only two antennas and a single receiver with a sum and difference pattern of 180° hybrid, and the orthogonality of an I/...

Preliminary analyses of radar cross section (RCS) in the design process of military weapon systems are very important. Recently, weapon systems such as missiles and fighter jets are adapted for large-size electrical objects in preparation for the wavelengths used in radar. Therefore, it is difficult to pre-analyze the RCS through commercial simulation programs unless a high-performance computing power is provided. To solve these problems, we propose a near to far field transformation algorithm that can be applied to domain decomposition analyse...

Compact Meander Slot Magnetic Dipole Antenna for Wide-Angle Scanning
넓은 빔 스캔을 위한 소형화된 미앤더 슬롯 형태의 자기 다이폴 안테나

Jong-Sang Yoo, Hyewon Jo, Hyunyoung Cho, Jongwon Yu 유종상, 조혜원, 조현영, 유종원

A meander slot magnetic dipole antenna for vehicle-to-everything communication is proposed. The vehicle antenna is often mounted on the vehicle’s rooftop, and the proposed antenna has a wide beam width for V2X communication in this environment. Miniaturization of the array antenna is implemented. Simulation and measurement results show that, at 5.8 GHz, the proposed antenna has a peak gain of 5.3 dBi and a 3 dB beam width of 160° on a large ground area, exhibiting performance similar to that of a conventional antenna.

https://doi.org/10.5515/KJKIEES.2019.30.10.803

In this paper, the gain variation of a 60 GHz aperture-coupled patch antenna that is dependent on the position on the ground plane is investigated. Despite using the same antenna, the antenna gain is varied as a function of the antenna position on the ground plane with a constant size. The period of gain variation is approximately 0.9λ and the amplitude is fixed with approximately 5 dB. Twenty fabricated test vehicles were measured and compared with simulation results using HFSS software; the measurement and simulation resul...

IIn this paper, we describe a C-band high power amplifier(HPA) Monolithic Microwave Integrated Circuit(MMIC) design and measurement results for satellite transmitters. For a high output power of 20 W, a 0.25 μm GaN process was used and the HPA MMIC with a 2-stage cascade configuration was operated in Class AB mode for high efficiency. The fabricated MMIC has 29 dB gain, 43.3 dBm output power, and 48 % power added efficiency(PAE) with an MMIC size of 3.0 mm×1.8 mm over a frequency range from 5.0 GHz to 7.2 GHz and exhibits an...

https://doi.org/10.5515/KJKIEES.2019.30.10.814

This work reports a 900 MHz wake-up receiver developed using 0.18 μm CMOS technology to reduce the power consumption of a Wireless Sensor Node(WSN). It employs the on-off-keying(OOK) modulation scheme for low power operation. N-path passive filters and an ultra-low power LC digitally controlled oscillator(LC-DCO) were designed. Additionally, a Dual-IF was adopted for lower sensitivity. The chip was tested at 1.2 V supply for low power operation. The measured results showed that the sensitivity and power consumption were −8...

Design of a 30-GHz Frequency Tripler to Suppress the Fundamental Spurious Tone
기본 주파수 불요파를 억제한 30 GHz 주파수 3체배기 설계

https://doi.org/10.5515/KJKIEES.2019.30.10.823

A design for a 30-GHz frequency multiplier using a Samsung 28-nm fully depleted silicon-on-insulator process is presented. The basic topology of the tripler is a single balanced mixer, which up-converts the fundamental LO signal and the second harmonic tone from a push–push doubler to achieve the third harmonic tone. The method suggested controls the phase of the down-converted signal and the fundamental tone from LO feedthrough to cancel each other. Additional fundamental spur suppression of 9.4 dB was achieved by applying 90° phase-shift...

https://doi.org/10.5515/KJKIEES.2019.30.10.829

To provide adequate radar coverage in an area with mountainous terrain, we require multiple radar stations and complex beam operations to reduce the blocking area. Consequently, the distance between two radar stations is reduced, which causes radio interference due to insufficient frequency bands and reduces the detection performance of the radar system. To prevent this, interference must be detected and avoided. However, it is difficult to predict and respond to interference as the beam operation is complicated. In this study, we developed a m...

https://doi.org/10.5515/KJKIEES.2019.30.10.839

In this study, a 24-GHz frequency modulated continuous wave(FMCW) radar system was designed on an FR-4 board to demonstrate the feasibility of low-cost radar systems. As the FR-4 substrate has a large substrate loss, its thickness was carefully determined considering line loss and radiation efficiency. Additionally, to operate the radar chip in the industrial scientific and medical(ISM) band without using a phase locked loop(PLL), we superposed and used the triangular wave signal of the DAC and proportional to absolute temperature (PTAT) voltag...

Three types of metal–oxide–metal capacitors fabricated in a 65-nm CMOS process are compared. The HPP structure utilizing only the vertical electric field exhibits a higher capacitance density of 0.2, 0.64, and 0.76 fF/μm² as the number of stacked metal layers increase to four, six, and eight, respectively. The VPP structure, which utilizes only the horizontal electric field, exhibits a relatively small capacitance density of 0.27 fF/μm². In contrast, the PW structure using the verti...
