Abstract
One of the most essential components of
wireless communication systems, particularly
in mobile devices, is the antenna. Covering a
large range of operating frequencies while
preserving excellent system performance over
the whole operating frequency range is one of
the desired characteristics of antennas. As a
result, future antenna designs for mobile
devices would greatly benefit from the ability
to adjust the antenna's resonance frequency
without changing its physical size. This study
suggests a model for adjusting the ferrite
material's electromagnetic characteristics to
tune the inverted F-antenna's operating
frequency across a comparatively large
frequency range. It will be shown in this
suggested model that the electrical regulation
of the antenna's ferrite material's permeability
successfully results in a notable change in its
resonance frequency and, therefore, an
increase in the communication system's
overall performance.
