What is Dual‐band Circular Slot Antenna Design for Circularly and Linearly Polarized Operations about?

## Abstract The dual‐band circular slot antenna utilizing the embedded arc‐shaped metallic strip for the circularly polarized (CP) and linearly polarized (LP) operations is presented in this letter. The experimental results show that the resonant frequency of low‐band for CP mode is utilized the protruded arc‐shaped metallic strip, which extends current route to make the fundamental resonant mode shifted to the lower frequency band. The high‐band for LP mode, which has the similar current distribution to that of the fundamental mode of the conventional circular slot, is employed the first‐higher order resonant mode of the circular slot. Two measured input impedance bandwidths of the proposed design are 23.2% and 18.8%, respectively, and the measured bandwidth of low‐band with an axial ratio (AR) of less than 3.0 dB is 14.5%. The operating bands show the broadside radiation patterns with 1.7–2.7 dBic CP gain and the peak antenna gain of 3.6–4.3 dBi, respectively. © 2010 Wiley Periodicals, Inc.
