Optimization of rod antennas of mobile phones. (English) Zbl 1083.90026
Summary: Two types of rod antennas for mobile phones are optimized so that the radiated energy absorbed by the head or body of the user is reduced and the radiation intensity to other areas, especially to the receiver, is increased. The mathematical modelling of this problem leads to an infinite-dimensional bicriterial optimization problem. It is shown that this optimization problem and a discretized version of this problem are solvable. The relationship between the infinite- and finite-dimensional optimization problem is investigated. Numerical results are presented for mobile phones working with the GSM standards 900 and 1800.
