Abstract

A miniaturized wideband Vivaldi antenna is presented in this paper. The proposed antenna is compact in size, has wide bandwidth and high radiation efficiency. The antenna is designed on FR-4 substrate with overall dimensions of $20\times17$ $mm^2$. The resonating frequency of the reported design is observed as 5.8GHz and impedance bandwidth is 2.67GHz (4.94GHz - 7.61GHz). The simulated radiation efficiency and gain are approximately 98.9\% and 3.66dBi, respectively. The proposed design finds its applications in IoT, 5G, Wireless LAN (WLAN), Intelligent Transportation System (ITS) and Radio Frequency IDentification (RFID).
