摘要：Objectives : To design a triple band microstrip delete patch antenna to be used mainly for satellite communications. The structure may be utilized additionally for RF devices and aviation. Methods/Statistical analysis : The proposed geometry uses numerical Finite Element Method to subdivide a large problem into small and simple finite elements. The applied simple equations modelling these finite elements are then stacked into a wider system of equations that would represent the entire problem. Various methods from the calculus of variations then approximate a solution by minimizing an associated error function. The proposed antenna geometry uses a 1.6 mm FR4 epoxy substrate with a probe feeding technique. The used software is HFSS. The design has been analysed in terms of reflection coefficient, bandwidth, radiation pattern, gain, directivity and VSWR. Findings : Using HFSS based on FEM, the design has been analysed in several aspects. Compared to both single band rectangular and circular reference MSA’s, the proposed multi band design offers highly improved characteristics as listed in Table. Application/Improvements : The structure is suited mainly for satellite applications. The 50 MHz bandwidth extending from 3.79 GHz to 3.84 GHz may be used for satellite communications and fixed microwave, the 80 MHz bandwidth from 4.63 GHz to 4.71 GHz for fixed satellite applications and the 210 MHz bandwidth extending from 5.21 GHz to 5.42 GHz may be used for RF devices, satellite communications and aviation.
