Background/Objectives: To design a single band microstrip shivling patch antenna intended to serve aviation communication including radio location and aeronautical radio navigation.

Methods/Statistical analysis: The proposed geometry uses numerical Finite Element Method (also called the finite element analysis) technique that attempts to find approximate solutions to boundary value problems for partial differential equations. The proposed antenna geometry uses a FR4 epoxy substrate with a coaxial/probe feeding technique. The design has been analysed in terms of reflection coefficient, bandwidth, radiation pattern, gain, directivity, VSWR and field overlays.

Findings: Using HFSS based on FEM, the design has been analysed in several aspects. Compared to a conventional rectangular MSA, the proposed structure has a gain higher by a factor of 13.36 dBi and a bandwidth improvement of 39.07%. The design is thus ahead in terms of its functionality and results compared to the rectangular counterpart.

Application/Improvements: The novel structure may be used for aviation communication including radio location and aeronautical radio navigation.
