In this paper, the design of a single-feed triple-band circularly polarized Spidron fractal slot antenna is presented. The proposed antenna is composed of a Spidron fractal slot, a Z-shaped slit, and two L-shaped slits to realize triple-band circular polarization operation. A simple 50› microstrip line is utilized to feed the proposed antenna. A conducting re∞ector is also used to reduce back radiation, thereby enhancing the forward antenna gain. The proposed antenna has total dimensions of 40:7mm£40:7mm£18:52mm (0:42‚£0:42‚£ 0:19‚) and was fabricated and tested. The experimental results show that the proposed antenna has i10dB re∞ection coe-cient bandwidths from 2.76GHz to 3.13GHz and from 3.56GHz to 6.22GHz. The measured 3dB axial ratio bandwidths are 2.28% (3.04{3.11GHz) for the lower band, 7.15% (4.18{4.49GHz) for the middle band, and 2.6% (4.93{5.06GHz) for the upper band. The peak gains within the i10dB re∞ection coe-cient bandwidths are 3.41dBic and 6.29dBic, respectively.
