| Popis: | The electromagnetic field recorded outside neurons, such as the scalp, is the result of different ions moving from synapses to soma and further to terminal buttons. This phenomenon can be displaced from low frequency in the microwave field using the corresponding changes of space and time, and the dendritic tree or axons could be modeled as the transmitting or receiving antenna. A compact microstrip antenna modeling the topology of biological neurons is investigated in this paper by using the spatial configuration given into the NeuroMorpho.org data base. This is a continuation of some previous research of authors and is focused on the influence of partial changes of dendritic tree segments, highlighted by changing characteristics of resonance and radiation in free space. The morphometric structures have been translated in the field of microwaves using microstrip line networks. The comparative modeling and simulation results regarding to multi-band response obtained by solving Maxwell's numerical equations in frequency domain for initial geometric configuration and when one of the dendritic tree branches is functional affected are presented in this paper. This kind of antenna is a natural correspondence of the fractal antennas described in the literature for their advantages regarding small sizes and multi-band response. |
