Photonic Bandgap Hepta-Band Stacked Microstrip Antenna for L, S and C Band Applications

This paper proposed a novel design of hepta-band microstrip patch antenna which is realized by a rectangular patch. The proposed patch antenna resonates between 1 and 9 GHz at seven distinct frequencies which covers L-, S- and C-band. The proposed microstrip patch antenna was designed using IE3D v. 15.00 simulation tool and have to achieve seven distinct band by using the combination of photonic band-gap (PBG) structure and stacking. The reflected power and resonating frequency of each bands are - 28.43 dB, - 14.57 dB, - 14.47 dB, - 21.53 dB, - 14.32 dB, - 29.47 dB and - 12.20 dB at 1.72 GHz, 2.36 GHz, 3.08 GHz, 3.64 GHz, 5 GHz, 6.16 GHz and 7.32 GHz respectively. And also, have shown its performance improvement by the use of the PBG structure and stacking.
