“…The measured results have good agreement with the simulated results. , a great deal of methods and designs have been proposed with the efforts of many researchers, such as slot antennas [1,2] and patch antennas [3,4]. These antennas achieve the tunable frequency by modulating the values of the structure parameters through optimization and simulation, which means that the manufactured antenna cannot be modulated anymore and is limited in practical engineering.…”

agreement between simulation and measurement is achieved while the reflection coefficient of the antennas is less than 28 dB in the 55-65-GHz band. Figures 12 and 13 show the radiation pattern of the fabricated antennas in the E-plane and H-plane. The rows of the metalized via holes placed around the edge of the substrate eliminate the existence of a half-mode SIW that could be a source of undesirable parasitic radiation. In this way, the Eplane radiation pattern of the proposed antennas has a lower ripple. The simulated H-plane radiation patterns are affected by the reflections from the metal block of the transition. In the case of the fabricated antennas, these reflections are suppressed using a high-frequency absorbing material and thus the transition has a very low influence on the radiation pattern. The measured Hplane radiation patterns are affected by an antenna positioner holder in the left half plane (elevation angle from 2170 to 210 ). The measured gain patterns of the antennas validate sufficiently the simulated ones. CONCLUSIONIn this letter, two SIW slot antennas have been proposed for the 60-GHz band. The antennas are characterized by low profile, compact size, low-cost fabrication, easy to design, and the ability to produce two different radiation patterns in the wide frequency band depending on the placement of the group of slots. On the basis of our research interest, the one-sided slot antenna is utilized for channel characterization of 60-GHz body centric communications and the double-sided slot antenna for experimental measurement of 60-GHz intravehicle signal propagation.A broadband, high-gain substrate-integrated waveguide (SIW) slot antenna fabricated on a PCB is presented in this article. Measured return loss reaches 25 dB at 45 GHz with the bandwidth of 4.72 GHz. The simulated gain is 9.6 dBi at 46.2 GHz and the efficiency is 96%. The measured gain is 7.8 dBi at 46.2 GHz. Good agreement is achieved between measured and simulated antenna patterns and return losses. It is shown that the antenna behavior can be enhanced by oversizing the bottom ground and properly selecting dimensions of top metal.

“…Many antennas using SIW technology have been designed. For example, the W‐band SIW horn antenna , fabricated on PCB produced 1 GHz of bandwidth with a simulated gain of 9 dBi, fed by a WR‐10 waveguide. A 60 GHz SIW horn fed by CPW was proposed in and demonstrated bandwidth of 6.3 GHz and gain of 14.4 dBi.…”

“…Nevertheless, horn-antennas were the finest option to attain maximum gain due to restricted fabrication and measurement facilities in the mm-wave frequency range up to 60 GHz [3]. Conversely, several fabrication technologies including SIW, MEMs and LTCC reduce the volume of the conventional horn antennas [4][5].…”

“…Conventional high gain millimeter-wave antennas, such as a horn antenna or a parabolic reflector antenna, are bulky. So the attention of researchers is dominantly focused on the design of low-profile antennas [2][3][4][5][6][7][8][9][10][11][12][13].…”

“…Since the SIW technology is a very promising candidate for the implementation of millimeter-wave antennas and circuits, other mm-wave SIW based high gain antennas were proposed [5][6][7][8][9], e.g. a slot array antenna [5], Yagi antennas [6,7], and SIW horn antennas [8,9]. However, a narrow operating bandwidth is the common feature of all those antennas.…”

A substrate integrated waveguide (SIW) offset parabolic antenna is proposed in this letter. The antenna consists of four main parts: a feeder with a horn radiator, a parabolic reflector, parallel plate metal blocks, and a dielectric load. The configuration of the horn and parabolic reflector is based on the parabolic reflector principle. The parallel plate metal blocks and the dielectric load improve the impedance matching and radiation performance of the antenna. Measured results show that the antenna is very well matched in the V‐band and the gain of the antenna in end‐fire direction varies from 13.2 dBi to 16.8 dBi. © 2016 Wiley Periodicals, Inc.
