摘要：

In this letter, a new model of antenna with Jerusalem crosses (JC) as fractal slots for circular polarization applications is designed. The proposed slot antenna has a fractal cross formation with four Jerusalem crosses (JC) to achieve wide bandwidth and a compact size as well as circular polarization. A T-shaped feed line is implemented in the proposed antenna for improving the bandwidth while the interaction of the feed line with cross-shaped slots makes circular polarization. The proposed antenna shows bi-directional pattern and bandwidth at 2.42-3.0GHz with VSWR < 2, which can be used in WiFi and Bluetooth applications with a gain of 3.5 dBi. The proposed fractal antenna size is 40 x 40 mm, and it is designed and fabricated on an FR-4 low-cost substrate with thickness of 1.6mm. It is simulated by HFSS full wave software. In addition, the experimental results are presented and compared with the simulation for VSWR, radiation pattern and axial ratio.
