The design of a microstrip‐fed annular‐ring slot antenna (ARSA) with circular polarization (CP) radiation is initially studied. To obtain CP radiation with broad 3‐dB axial ratio (AR) bandwidth that can cover the WiMAX 2.3 GHz (2305–2320 MHz, 2345–2360
Microstrip-Fed Ring Slot Antenna Design With Wideband A microstrip-fed circular ring slot antenna (CRSA) with a fundamental mode at 2.45 GHz is initially studied. To suppress the additional harmonic modes excited by the ring slot, a single inverted U SINGLE-FEED CIRCULARLY POLARIZED ANNULAR SLOT … 2018-1-14 · bended microstrip line and a cavity back. Dual-band CP radiation can also be achieved by using a spiral slot [13], or a CPW-fed annular slot with two perturbation strips [14]. In [15], a square microstrip patch antenna embedded with four slots and a crossed slot can generate dual-band CP radiation. But all these designs in [13{15] have a limited antenna | Techn.

INTEGRATED COMPACT CIRCULAR POLARIZATION ANNULAR … ANNULAR RING SLOT ANTENNA DESIGN FOR RFID READER Jun Lin Zhang and Xiao Qing Yang* College of Electronics and Information Engineering, Sichuan Univer-sity, Chengdu 610065, P. R. China Abstract|An integrated compact circular-polarized annular ring slot antenna is proposed in this paper. It consists of an annular ring slot Annular Slot Loaded High-Impedance Ground Plane - ECE/CIS A conventional slot ring without a grounded dielectric will radiate at a frequency determined by the guided wavelength of the slot. That is, an annular slot antenna will radiate its fundamental mode at a slot radius of [2] Annular Slot Loaded High-Impedance Ground Plane
