摘要：Background/Objectives : To design a mono band microstrip slotted power button antenna intended to serve aviation communication involving 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 tries to approximate boundary value problem solutions for the case of partial differential equations. It subdivides a larger problem into small and simple finite elements which are represented by simple equations that are finally assembled into a larger system of equations representing the entire problem. Different methods from the calculus of variations are used to approximate a solution by minimizing the associated error function. 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 hexagonal shaped MSA that has been used as a reference, the proposed structure has an improved gain by a factor of 3.72 dBi and a reflection coefficient reduced by a factor of 1.91. Application/Improvements : The structure is fit to be used for aviation communication/radio determination including radio location and aeronautical radio navigation.
