Abstract :
A novel method is introduced which enables the use of a tunable narrowband antenna within a wide frequency range. The resulting antenna is able to operate in multifrequency bands simultaneously. In addition, the number of frequency bands and their center frequencies can be changed dynamically. A time domain simulation is provided using a simple circuit model for two simultaneous frequency bands. A tunable antenna is designed and tested for two simultaneous frequency bands as well.
