Abstract: Modes can be controlled (tuned, shaped) using correctly placed excitation elements [1], as well as by introducing fixed points, e.g. grounding points, slots, resonant lengths etc. • Initial CMA designs without excitations: • Can address impedance matching in a second step, either through rigorous optimization or including a matching circuit • Bandwidth of the resonant modes gives a good indication of the actual antenna bandwidth • CMA gives a broader understanding of how the antenna operates • Modal currents, modal radiation patterns • Can be applied to make more informed design decisions • At higher frequencies where multiple modes are resonant it is more challenging to isolate single modes, especially if a only a single excitation is available
