Abstract:
Common problem of antenna mathematical model synthesis for mobile radio communication in theoretical and practical sense is solving two connected partial problems: new antenna design, ensuring necessary impedance and spatial characteristics; new antenna design, ensuring high level of protection from environmental conditions. Analysis of native and foreign applications for antenna systems computer aided design showed that in most cases classical approach is used when work is done consecutively. In that case control of several groups of factors and limitations in order to reach optimal solution is applied on different design stages. Antenna design algorithms for stages of electrodynamics modeling and modeling of environmental impact are listed. To ensure high operational properties it is suggested to build complex antenna mathematical model for mobile radio communications which incorporates electrodynamics modeling as well as environmental and mechanical factors. As en example solution was found for log-periodic antenna. Results of calculating VSWR for original and refined antenna model are listed, including for antenna glaciation.
