Abstract
This paper presents a design procedure for a singly‐fed circularly polarized aperture‐coupled multilayer microstrip antenna (SF‐ACMMA) for INMARSAT ground terminal applications. In the design, low‐cost foam with low permittivity is used for enhancing the impedance bandwidth of antenna. The impedance bandwidth for VSWR ≤ 2 and circular polarization bandwidth for axial ratio (AR) ≤3 dB reach to 18.8% (1.45 to 1.75 GHz) and 12.3%, respectively. A gain of 9.4 dBi is also achieved. These measured results verify the applicability of design. © 2003 Wiley Periodicals, Inc.
