Novel UWB Microstrip Antenna Structures with Defected Ground Structure

Indonesian Journal of Electrical Engineering and Computer Science, 2018
<p>This paper presents the design of new compact printed antennas for Ultra Wide Band applications, fed with a microstrip-line. The proposed designs consist of a patch antenna with defected ground, which are fed by 50Ω microstrip transmission line. The frequency range is 3.1-10.6 GHz which is the Federal Communication Commission (FCC) band of UWB.
