Eunjung Kang, Cheolhun Seo, Hosung Choo 강은정, 서철헌, 추호성

J. Korean Inst. Electromagn. Eng. Sci. 2021;32(10):872-877.
https://doi.org/10.5515/KJKIEES.2021.32.10.872

In this study, we propose a high-directivity low-profile patch antenna for microwave wireless power transmission systems. The proposed antenna is analyzed according to fundamental and higher-order modes based on the cavity theory, and high-directivity characteristics are derived with an optimum patch size using the directivity formula. To achieve low-profile characteristics, a high-directivity patch antenna is designed by applying the optimum permittivity, which can simplify the structure and lower the manufacturing cost. For a side length of 0...

https://doi.org/10.5515/KJKIEES.2021.32.10.878

The fabrication and design of a liquid crystal (LC)-based X-band reflectarray antenna are described. A high-efficiency reflectarray antenna was achieved by defining and optimizing its efficiency parameters. Considering the high loss tangent of the LC, the equivalent circuit of the lossy medium was modeled, and the reflection loss of the unit cell was minimized. Furthermore, a 2×2 patch array antenna was employed to optimize the spillover and taper efficiency. To minimize blockage loss, the reflectarray was designed by employing offset feedin...

https://doi.org/10.5515/KJKIEES.2021.32.10.888

An eight-channel transmit/receive module (TRM) was designed for a wideband electronic warfare multiple threat jamming transceiver. In the system, the TRM amplifies a multijamming signal from a multibeam transceiver module and a small radio frequency (RF) signal from an antenna. In TX mode, it has an output power of more than 43 dBm for a continuous wave. In RX mode, it has a gain of more than 10 dB and noise figure of less than 5 dB. The voltage standing wave ratio is less than 2:1, and the TX and RX path isolation is 50 dBc or more. The RF sig...

24 GHz Long-Range Radar Transmitter Using Beam Switching
빔 스위칭을 이용한 24 GHz 장거리 탐지용 레이다 송신기

Jae-Eun Lee, Jeong-Bae Yoon, Dong-Hwi Kim, Reen Song, Byung-Sung Kim 이재은, 윤정배, 김동휘, 송림, 김병성

https://doi.org/10.5515/KJKIEES.2021.32.10.894

This paper proposes a three-dimensional 24 GHz frequency modulated continuous-wave (FMCW) radar transmitter for long-range detection. The proposed transmitter implements seven switched vertical fan beams from 15° to −15° for high effective isotropic radiated power (EIRP) and vertical angle detection. Instead of using lossy electronic switches and large passive beamforming networks, the beamforming transmitter is achieved by directly switching the power amplifier, which drives a sectoral series patch array antenna. The EIRP of each beam is ...

https://doi.org/10.5515/KJKIEES.2021.32.10.901

In this study, we analyzed the signal characteristic changes in a single-ended dual-stripline configuration, which is often used in high-speed memory system chip packages and module circuit boards, and developed a methodology to mitigate crosstalk. Although using a dual-stripline configuration can result in a reduced number of layers and increased cost of PCB, it inevitably deteriorates the crosstalk and reflection characteristics formed by capacitive coupling. This is because there is no reference layer between the two signal layers. We analyz...

https://doi.org/10.5515/KJKIEES.2021.32.10.916

We propose a method of moments (MoM) matrix assembly method for electromagnetic scattering analysis of large-scale complex materials composed of impedance and dielectric media. Material information is assigned to each triangular mesh of the discretized surface, and the interaction among the meshes is calculated. If several meshes are assigned to one edge, the half-Rao-Wilton-Glisson (RWG) basis function is used to calculate the Z matrix elements. Iterative physical optics (IPO) analysis is performed based on the local tangential approximation f...

https://doi.org/10.5515/KJKIEES.2021.32.10.925

This paper presents the calculation of the radar cross-section (RCS) of an arbitrary scatterer with a perfect electric conductor by using the incremental theory of diffraction (ITD), a high-frequency technique. The reflected field at the surface of the scatterer is calculated using conventional shooting and bouncing rays (SBR), and the diffracted field at the edge is calculated using the ITD. The proposed method is verified by calculating the monostatic and bistatic RCS of a scatterer composed of two cubes of different sizes and comparing it wi...

Photonics-based radar system is designed and fabricated for X-band frequency-modulated continuous-wave (FMCW) radar with optical devices, and it is demonstrated by conducting system integration and far-field tests. The photonics-based radar system generates broadband linear frequency-modulated (LFM) signals with a bandwidth that is 20% of the X-band of the center frequency for high-resolution inverse synthetic-aperture radar (ISAR) images by using an electro-optical modulator. It directly processes broadband target signals with photonics device...
