The analysis and synthesis of conformal printed antennas on ellipsoidal structures are investigated. The originality comes from the use of a computer algebra system to generate the polynomial expression of the zeros of the characteristic equations. Fast and accurate expressions for the resonance frequency are given for an ellipsoidal radiating...

An original and accurate analytical model is developed for elliptical microstrip antennas. This model is based on a modified Wolff cavity model. The input impedance is calculated from an equivalent circuit with a rigorous probe model. Numerical and experimental results on the resonance frequency and the input impedance for different...

An accurate synthesis model applied to multilayer probe-fed microstrip antennas, is presented. An appropriate and original use of a symbolic algebra system and a modified Wolff cavity model allow to obtain, with a low computing time, the optimal size and the shape of the antenna, with its uncertainty, versus the physical and geometrical...
