Abstract
In today’s mobile device market, there is a strong
need for efficient antenna miniaturization. Tunable antennas are
a very promising way to reduce antenna volume while enlarging
its operating bandwidth. MEMS tunable capacitors are state-ofthe-
art in terms of insertion loss and their characteristics are
used in this investigation. This paper uses field simulations to
highlight the trade-offs between the design of the tuner and the
design of the antenna, especially the impact of the location of the
tuner and the degree of miniaturization. Co-designing the tuner
and the antenna is essential to optimize radiated performance.
