This paper proposes a design of a high-gain slotted array waveguide antenna of a radar system to prevent accidents at sea. The proposed antenna has a reduced size, 2⁻³, of the broad wall length and the narrow wall length of the WR-51 standard waveguide. To realize a low profile and high gain in comparison with the WR-51 standard waveguide slotted array antenna, the parameters, such as the slot length, width, offset, and distance between slots, were precisely calculated using the iterated simulations. The reflection coefficients and...

https://doi.org/10.5515/KJKIEES.2020.31.12.1004

In this paper, an effective method is proposed to optimize the amplitude weight of a symmetrically arbitrarily shaped planar array, whose shape is not typical, such as a rectangle or a circle, to suppress the sidelobes to less than a certain level in the entire space excluding the main beam region. After selecting a conventional Taylor weight as an initial weight and calculating its radiation pattern in the entire visible space, all the peak values of sidelobes larger than a specified level are limited to that value by adding a small perturbati...

https://doi.org/10.5515/KJKIEES.2020.31.12.1013

This paper proposes new microstrip directional couplers with high directivity using current path detour to compensate for unequal even- and odd-mode phase velocities in the U-NII upper band (5.725~5.850 GHz). The proposed method involves matching the phase velocities of even and odd modes by designing a longer current path for the odd mode, whose phase velocity is faster than that of the even mode. The proposed idea is demonstrated by the design of two directional couplers: one is a directional coupler with triangular edges on each side of the ...

Implementation of Low-Loss Compact 4×4 Butler Matrix in Ku-Band
Ku 대역 저손실 소형 4×4 버틀러 매트릭스의 구현

Hosung Joo, Soon-Young Eom 주호성, 엄순영

J. Korean Inst. Electromagn. Eng. Sci. 2020;31(12):1020-1032.
https://doi.org/10.5515/KJKIEES.2020.31.12.1020

The Ku-band (12~18 GHz) is mainly used for long-range satellite communications and radar applications. Because the signal power is weak in a long-range communication, it is important to reduce the loss of the transmitter and receiver. In this paper, we propose a low-loss compact 4×4 Butler matrix structure that operates in the range of 15.7~16.7 GHz. To achieve low-loss characteristics, a low-loss transmission line was designed based on the suspended transmission line. To miniaturize the structure, the internal circuit of the Butler matrix w...

In this paper, we describe an automatic calibration method and test results for a tile-type subarray consisting of a Tx phased-array antenna for Ku-band satellite communication. For array antenna calibration, the aperture electric field distribution, which is supported by the planar near-field measurement system, is used to minimize the phase variations across the array aperture. All the calibration procedures are performed automatically through interoperation between the planar near-field measurement system and array antenna control board. As ...

An 3D radar system can detect the distance, azimuth, and altitude of targets. The radar acquires target information using an electronic or mechanically steered narrow antenna pattern. It calculates the target altitude using the detected information. In addition, angular accuracy is improved by applying various methods such as monopulse. The radar angular accuracy is affected by external factors such as multipath effects that are caused by various factors such as the radar installation environment and the flight altitude of the target.

A dielectric barrier discharge (DBD) plasma generator with a face-to-face multilayer structure for radar cross section (RCS) reduction is designed. The generator includes two electrodes of 16×0.5 cm² size, facing each other. Because the electrodes are on the plane that is parallel to the direction of the incident wave, the effect of the generator on the RCS of the target is significantly reduced, particularly when compared to conventional parallel plate-type generators. This simplifies the design procedure for the DBD generator an...

A periodic aperture array structure combined with a lossy ground conducting layer was analyzed using the method of moments and was shown to produce near-perfect absorption. Rectangular aperture and rectangular loop aperture geometries were considered as examples of a unit cell of aperture. The numerical results for the reflection coefficient for the case where the unit cell of the aperture was rectangular were compared with those obtained by using commercially available software, such as HFSS and CST MWS, to validate the analysis method.
