Abstract :
A miniaturized antenna consisting of a square-ring monopole and a tapered ground plane has been designed and analyzed at around 210 MHz. Simulated results indicate that a 13 dB improvement in impedance matching can be achieved by placing an identical parasitic antenna element directly underneath the active one. The miniaturized antenna, with overall dimensions of approximately one tenth of a wavelength (0.1lambda), can be used for RFID or sensor applications.
