Printed dipole with slot EBG structures with Artificial Magnetic Conductor and band-notched behaviours

摘要

This paper presented a printed dipole with slot Electromagnetic Band Gap (EBG) that has both Artificial Magnetic Conductor (AMC) and band-notched performances. Compared to a reference square patch EBG, printed dipole with slot EBG exhibits band-notched behaviour at the out-of-band frequency with 10dB maximum suppression. The antenna maintains a peak gain of 8dB at 2.4GHz resonance due to High Impedance Surface (HIS) feature. Initial investigation for a tunable notch band was also explored. Promising results give future possibilities for practical tuning with varactor diodes.
