Design of Optimized Cylindrical Structural Antenna with Quasi Length Insensitivity using CMA

Résumé

This paper deals with the design of cylindrical structural antennas, whose dimensions are larger than the wavelength and which is usually difficult to handle due to higher order modes excitation. Using CMA (Characteristic Mode Analysis) gives us the current modes of such structure. We then selected the modes that met our specifications in terms of radiation pattern and currents and excited them through slots. We show that this structural antenna have a 6% of bandwidth with a max gain of 5.76 dBi at 4.3 GHz.
