PROPOSED MODEL FOR FREQUENCY TUNING OF FERRITE-BASED INVERTED F-ANTENNA
SINOPSIS
Nowadays, the technology of mobile wireless communications is advancing so quickly, and hence the need for efficient and reliable components of the wireless systems is rising as well. One of the most important and crucial components of the mobile devices is the antenna, where the operational characteristics of the wireless system are designed around the directional properties of the antenna.
Consequently, the tunable antenna that covers a wide range of operating frequencies without altering its physical dimensions, becomes so critical, and expedient in successful designs of mobile devices. Although the average terminal size has decreased drastically, the internal antenna has been designed into standard solutions in order to meet the new design requirements, taking into consideration the strict limitations set on the energy absorbed by the users of mobile devices.
In this paper, we are proposing a model for frequency tunable ferrite-based inverted F-Antenna that can cover a wide range of frequencies, by altering the magnetic properties of the ferrite material of the antenna.
In this proposed model, the resonant frequency of the antenna can be significantly shifted by altering the permeability of the ferrite material of the antenna, and without changing the physical dimensions of the antenna. The resonant frequency shift gives the flexibility to operate the antenna over a wide range of frequencies which leads to an overall enhancement of the communication systems.
