Diplexers are one of the key devices required to separate uplink and downlink signals in transceivers using a single grounded antenna. This study presents the design of an X-band diplexer for satellites. First, bandpass filters of the transmitter and receiver are designed. Next, an X-band diplexer is designed by combining the two bandpass filters. Simulation results show that the insertion loss is less than 0.75 dB and the return loss is more than 20 dB. Additionally, the channel isolation property is greater than 103 dB, thereby satisfying the...

In this study, a frequency-selective radome in the millimeter-wave band with excellent incident-angle stability is designed. The hybrid structure comprising the designed radome combines a multilayered composite material, which has a rectangular loop-type FSS (frequency selective surface) structure with frequency-selective transmission characteristics in the millimeter-wave band. It has a low transmission loss of ≤1 dB in the pass band and a high blocking characteristic of ≥10 dB in the X-band for polarization TE (transverse electric). Addit...

FMICW radars detect and track targets using frequency information based on the distance and velocity of the target. Therefore, the phase noise of the received signal and the frequency resolution must be minimized to ensure detection and tracking accuracy of the radars. However, as the signal frequency increases, the phase noise degrades. Therefore, the design requirement of the phase noise is important for radar using high-frequency signals. In this study, the phase noise of the transmission signal (FTX), local oscillation signal (FLO1, FLO2), ...

In this study, an X-band GaN monolithic microwave integrated circuit (MMIC) low-noise amplifier is designed and fabricated for RF transceiver modules using a 0.2 μm ETRI GaN HEMT process. Through the application of a feedback microstrip line at the source of the transistor, the amplifier operation is stabilized, and a compromised impedance trace of the input impedance and noise matching is obtained, which minimizes the degradation of the maximum available gain and minimum noise figure. The developed MMIC low noise amplifier,...

Commercial products, such as the National Instrument's USRP (universal software radio peripheral) products and the latest instruments, provide functions to receive and analyze signals. Because the characteristics of the target signal are diverse, these systems are designed to receive a wideband signal to a narrowband signal and provide functions for extracting a desired signal and analyzing it in detail if necessary. In the past, these functions were implemented in the form of hardware, such as FPGA (field programmable gate array) and DSP(digit...

In this study, ferrite wall structures are proposed for reducing leakage magnetic field in a wireless power transfer system with a bipolar magnetic coupler structure in the form of a ferrite core inductor. In the proposed framework, the magnetic field of the transmitting coil remains on the ferrite wall, and the leakage magnetic field is minimized. However, when the magnetic field of the transmitting coil is induced in the ferrite wall, the mutual inductance and coupling coefficient decrease. Therefore, in this paper, the height of the ferrite ...

To map the surrounding environment using a radar sensor, both radar detection results and robot’s motion information are required. In general, an additional inertial sensor is required to acquire motion information of the robot. In this study, a method for estimating a robot’s ego position from radar detection results without the aid of other sensors is developed. First, the absolute positions of the detected targets are determined by comparing the radar detection results in two consecutive frames. Next, the position of the robot in the new...

https://doi.org/10.5515/KJKIEES.2022.33.5.403

When detecting targets using radars, errors may occur owing to the refraction of electromagnetic waves. It is necessary to analyze these errors by predicting the true location of the target through a path analysis of the electromagnetic wave. In this study, we develop a method for analyzing the target detection error based on the operating conditions of the radar. To consider the radar operating conditions, we calculate the refractive index for the radar installation location and analysis area, and develop a process for predicting the refractio...

This study presents a Ka-band direct-conversion receiver using a 28-nm CMOS (Complimentary Metal Oxide Semiconductor) process for radar applications. The designed receiver includes a LNA (Low-Noise Amplifier), Mixer, and Baseband amplifier. The LNA adopts a two-stage cascode amplifier structure. Then, the mixer is a single-balanced passive mixer with low flicker noise. At the end, the baseband amplifier is a transimpedance amplifier with fat FET (Field-Effect-transistor) for low flicker noise and current-mode operation of the mixer. The LO (Loc...
