Abstract

A new design of coplanar waveguide (CPW)-fed antenna with circular polarization (CP) and excellent impedance matching is presented. In this design a pair of circular-shaped slits is applied to opposite corners of the slot for enhancing the impedance matching and realizing bandwidth of 134. 43 % across 2. 98-15. 20 GHz for VSWR ≤ 2. Furthermore, this structure exhibits axial ration bandwidth (ARBW) of 36. 22 % across 4. 43-6. 39 GHz by embedding two inverted L-shaped ground arms in the slot. The total dimension of the proposed antenna is 25 × 25 × 0. 8 mm3. This new design has advantages of, supporting the ultra-wideband (UWB) systems and covering the WLAN spectrums with 3 dB CP radiation and VSWR ≤ 2 simultaneously. The numerical and experimental results of the antenna explain the superiority of the proposed antenna performance in comparison with recent similar works.
