Abstract

A notched flower-shaped patch wideband MPA antenna is designed with defected ground (DGS) to realize magnified performance for the various wireless application. The several modes effectively excited in antenna and also higher order modes merging efficiently to enable wider impedance bandwidth. The current distribution is improved with notched flower-shaped patch and efficient stimulation of multiple modes, while the enhanced impedance matching and extension of bandwidth are contributed with defective ground. The antenna has overall size measuring length of 1.14λ, width of 1.14λ and height of 0.04λ. The result exhibits a return loss lower than -10 dB across 5.12 GHz to 8.58 GHz, with 5.58 dB peak gain. This range supports wide range of wireless application, such as Wi-Fi 6/6E, Sub-6 GHz 5G NR, short range automative radar and C-band satellite communication. The compact size makes it appropriate for integration on space constrained device.
