Microstripline feed annular ring slot microstrip antennaSrilakshmi.AResearch Scholar, JNTUH & Associate Professor ECECircular ring slot antenna size is small coplared to circular disc antenna. Many others analyzed about the circular ring slot antenna with parasitic patch around the slot. A novel design of a microstrip-fed shorted square-ring … A microstrip-fed CP square shorted ring-slot antenna has beeninvestigated and successfully implemented. The return loss char-acteristic and CP radiation performance can be controlled andimproved individually. The proposed antenna has several advan-tages at the same time which...

CPW-FED ANNULAR SLOT ANTENNA DESIGN In this work, a conventional annular slotted structure is employed as the reference antenna. Geometry of the annular slot antenna with a CPW-feed line is shown in Figure 1(a). In general, a microstrip slot antenna is very popular due to its compact, low-profile and easy to integrate with monolithic microwave DESIGN OF RECONFIGURABLE ANNULAR SLOT ANTENNA (ASA) FOR ...
