Abstract :
A novel and compact electrical loop antenna for an RFID reader at 433.92 MHz is proposed. Using modified and stacked patches, in-phase and uniform currents are excited so that an omnidirectional radiation pattern with a /spl phi/-component of the electric field is obtained. The antenna is analysed based on simulated and measured results.
