Polarization Reconfigurable Eccentric Annular Ring Slot ... Abstract: A microstrip-fed reconfigurable eccentric annular ring slot (EARS) antenna with switchable polarization is proposed. To generate orthogonal circular polarization (CP) radiations, two identical perturbation slots (PSs) are loaded below the eccentric ring-shaped slot. Miniaturization and Bandwidth Enhancement of a CPW-Fed ... 2. 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 A Compact Annular Ring Microstrip Antenna for WSN Applications A compact annular ring microstrip antenna was proposed for a wireless sensor network (WSN) application in the 2.4 GHz band. In this paper the major considerations of the conformal antenna design were the compact size and the impact on antenna's performance of a steel installation base. By using a ...
