abstract

  • In this paper, a low-profile, compact size, inexpensive, and easily integrable frequency reconfigurable antenna system is proposed.
    *e proposed antenna consists of an inverted-F shape antenna, capacitors, and switching PIN diodes. *e designed antenna
    element is fabricated on easy available and less expensive FR-4 substrate (εr � 4.4, tan δ � 0.02). *e switching diodes are
    incorporated within the radiating structure of the antenna design, and by changing the different states of PIN diodes, frequency
    reconfigurable response is achieved. While adjusting the different states of the diodes, the antenna resonates between 0.841 GHz
    and 2.12 GHz and covers six different frequency bands. *e proposed system has compact size of 44 × 14 × 3.2mm3. *e gain of
    the antenna is between 1.89 and 2.12 dBi. *e measurement results shows the good agreement with simulated results for different
    key performance parameters. Additionally, the proposed antenna shows omni-directional far-field characteristics for various
    different frequencies.
