Abstract
This research paper bestows a rectangular slot-loaded microstrip antenna in possession of DGS, which may give multi-band and the highest gain for C-band, X-band, and Ku-band applications. The distinct antenna structure is simulated through HFSS 13.0 simulation software for the illustrative investigation of enhanced gain. The newborn evolution of the advancement of wireless internet means of approach is concerned with the insistence on multi-band antennas. The investigation of nine-band frequency antennas is an achiever of 6.0350 GHz (Global Navigation Satellite System (GNSS)), 6.7950 GHz (Satellite TV), 7.46 GHz (Long-distance Communication), 8.5050 GHz (Terrestrial Broadcast Radar), 11.45 GHz (Space Communication), 13.35 GHz (detector), 15.06 GHz (Military), 17.24 GHz (Aerospace), and 19.05 GHz (Astronomical observation). The multi- band aspect is accomplished by novel U-slot cuttings and rectangular slots in the antenna. It resonates at quad- band without any patch or ground modification; when a U- slot cutting is made at the left and top of a patch, it resonates at six bands; and when rectangular slot cuttings are united at the ground plane, it resonates at nine bands. The slot length, width, and position are optimized to attain the highest gain. The achieved gains of the proposed antenna are 1.5865 dB, 1.1344 dB, 1.0416 dB, 0.92179 dB, 3.7586 dB, 6.2776 dB, 5.1998 dB, 14.679 dB, 5.4279 dB, 6.0350 GHz, 6.7950 GHz, 7.4600 GHz, 8.5050 GHz, 11.45 GHz, 13.3500 GHz, 15.0600 GHz, 17.2450 GHz, and 19.0500 GHz, In wireless communication, a successful multi-band antenna is advantageous.
