摘要：
This paper presents the design, fabrication, and measurement of a novel ultra-wideband (UWB) hexagonal fractal patch antenna. This antenna uses hexagonal shape with Koch snowflake fractal at its edges. The proposed antenna has been excited using microstrip feed. The measured result of this antenna offers the ultra wide-band characteristics from 3.265 GHz to 8.2 GHz. The antenna is practically fabricated and tested. Measured results show a good agreement with simulated results. The measured radiation patterns of this antenna are nearly omnidirectional in H-plane and bidirectional in E-plane. This antenna holds applications in many satellite communication transmissions, some Wi-Fi devices, cordless telephones, and weather radar systems. In this paper, an approach for multi-band antennas is proposed. First, a hexagonal patch is taken, it is fractured using Koch structure. The antenna shows compact dimensions with good S-11 and pattern performance to be adopted for UWB applications.
