Abstract: This invention discloses the design and performance evaluation of a kite-shaped multi-band wideband microstrip patch antenna intended for sub-6 GHz and emerging 5G applications. The proposed antenna demonstrates strong multi-band characteristics with resonant frequencies observed at 1.42 GHz, 3.60 GHz, 6.70 GHz, and 10.07 GHz, achieving excellent impedance matching with reflection coefficient (S11) values well below –10 dB. The inclusion of defective ground structure effectively modifies the surface current distribution, resulting in multiple resonant modes and enhanced bandwidth performance. The antenna exhibits five distinct operating bands with fractional bandwidths of 21.4%, 9.77%, 7.61%, 7.19%, and 14.63%, respectively, indicating wideband behaviour, particularly in the lower and higher frequency regions. The Voltage Standing Wave Ratio (VSWR) remains below 1.3 across all resonant frequencies, confirming efficient power transfer and minimal mismatch losses. Radiation analysis reveals a peak gain of approximately 6.2 dBi with stable radiation characteristics. The antenna shows a broadside radiation pattern, with nearly omnidirectional behaviour in the H-plane and multi-lobe characteristics in the E-plane due to higher-order mode excitation. Despite minor distortions introduced by the defective ground structure, the radiation performance remains suitable for practical wireless applications. Overall, the proposed antenna offers a compact, efficient, and versatile solution with multi-band and wideband capabilities, making it suitable for sub-6 GHz 5G communication, WLAN, IoT devices, and extended X- band applications.
