Double‐sided aperture‐coupled vertically mounted strip antenna

Abstract

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

Broadband cavity‐backed aperture‐coupled vertically mounted strip antenna

“…Earlier research has calculated some of the circuit‐element values, including n m , n v , ( Z 0v1 , β v1 ), ( Z 0v2 , β v2 ), Y b , n 10 , and B hm , Z 010 and β 10 , and Z r0 . To model the more complex structures such as the open‐ended waveguide with the VM substrate and the right‐angle VM line bend, numerical simulations can be used.…”

“…This paper proposes a new broadband antenna in the form of a cavity‐backed aperture‐coupled vertically mounted (VM) strip by extending the idea of the broadband aperture‐coupled waveguide transition . The VM strip antenna has been studied previously as an alternative solution to the full planar antenna element and array configurations for increasing bandwidth and design of freedom …”

“…4 The VM strip antenna has been studied previously as an alternative solution to the full planar antenna element and array configurations for increasing bandwidth and design of freedom. [5][6][7] An equivalent circuit of the proposed aperture-coupled waveguide transition was developed to explain the operating mechanism and to provide initial design parameters of the antenna. To investigate the equivalent-circuit model, the computed results based on this equivalent circuit were compared with those computed through the numerical simulation.…”
