An electrically small frequency reconfigurable antenna with a wide tuning range
Publikation/Tidskrift/Serie: IEEE Antennas and Wireless Propagation Letters
An electrically small frequency-reconfigurable antenna with a very wide tuning band is proposed. Three varactor diodes are used to achieve the tunable capacitance. With a modifled feeding structure, the measured tuning range of the fabricated antenna reaches from 457.5 to 894.5 MHz, and the tuning band enhancement is also explained through an equivalent circuit analysis.
