Design and Analysis of Novel Ring UWB Antenna

In this communication, the design and analyses of novel printed ultra wide band ring monopole antenna is presented. The recommended has a pretty small size 20 x 26 1.6 mm3 which on FR4 dielectric material constant 4.4 ad loss tangent 0.02. general geometry radiating part composed circular ring. defected ground structure corner points. feed placed in asymmetrical position with respect to x-axis as microstrip line. findings obtained by examining performance criteria are presented systematic way. results indicate that proposed suitable parameters at UWB frequency range.
