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 proposed
antenna is simulated and fabricated on FR-4 substrate with
overall dimensions of 20 x 17 mm2. 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).
