“…In this article, a novel aperture‐coupled microstrip‐to‐waveguide transition having a broad operating bandwidth and providing for a simple fabrication and assembly is presented. The basic circuit configuration is based on aperture‐coupled vertically‐mounted (VM) strip structures which have been introduced for the coupling and radiating elements . A parametric study and a sensitivity analysis were made in order to find the optimal design data and to investigate the tolerance issue, respectively.…”

A novel aperture‐coupled microstrip‐to‐waveguide transition is presented in this article. A vertically mounted strip has been inserted into the E‐plane of a rectangular waveguide in order to provide broadband characteristics and higher forward transmission efficiency. A parametric study was made in order to obtain the optimal design data for broadband, low loss, and high efficiency. In addition, a tolerance study proves that the proposed transition is robust in regards to mechanical assembly and alignment. An X‐band transition was designed, and the measured results demonstrate that the transition shows a broadband (49.5 % with a reference return loss of 10 dB), low insertion loss (0.41 dB), and high transmission efficiency (93.40 %). © 2017 Wiley Periodicals, Inc.

“…There has been increasing interest in wideband and multiband wireless communication and radar systems, which leads to a great demand in designing appropriate microstrip antennas . There have been recent studies on aperture‐coupled vertically mounted strip circuits and antennas, and the impedance and radiation characteristics of aperture‐coupled vertically mounted strip antenna (ACVMSA) have been examined . Along with the wideband antenna, much attention has been paid to multiband, especially dual‐band, antennas.…”

This article presents dual‐band designs of aperture‐coupled vertically mounted strip antenna (ACVMSA). Two vertically mounted (VM) patches on either side of the VM substrate are excited via the coupling aperture to support dual‐band operation. A parametric study is undertaken to examine the effects of the related structure parameters and develop a design strategy. It is known that each resonant frequency and the corresponding coupling amount can be controlled nearly independently of each other, giving an advantage for dual‐band ACVMSA design. In addition, the antenna supports the same linear polarization. The antenna designed was fabricated, and the measured results were found to agree well with those calculated. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:157–160, 2015

“…Contrary to our previous study [5], where the equivalent circuit values were obtained by invoking numerical simulation [6], analytic or semi-analytic (only a numeri-cal integration is involved) approaches are used in this paper for a simple and efficient calculation of equivalent circuit values. The circuit values nm, nv, and Ya can be calculated by the method described previously [4], [7].…”

A general analysis of an aperture-coupled vertically mounted strip antenna is presented to examine its circuit characteristics. Based on the present analysis, an equivalent circuit model is developed, and an analytic or semi-analytic evaluation of the related circuit element values is described. The effects of structure parameters on the antenna characteristics were studied with the developed equivalent circuit, and the design curves were obtained. To check the validity of the proposed analysis and design theory, two C-band antennas (5.0 GHz and 4.5 GHz) were designed and fabricated. Their computed characteristics, derived from the proposed network analysis, were compared with the measurement and simulation results. The error of the current model in predicting the operating center frequency was less than 0.50 %. In addition, the observed bandwidth was found to be comparable to the conventional microstrip antennas. All the results fully validated the efficiency and accuracy of the proposed analysis and network model.
