Two-Layer Stacked Microstrip Cylindrical Conformal Antenna Array With Cross Snowflake Fractal Patches

摘要

A novel, two-layer, stacked, high gain, microstrip, cylindrical conformal antenna based on planar cross snowflake fractal patches exhibits high gain and aperture efficiency. Its impedence bandwidth is 19.75 percent, from 5.23 to 6.54 GHz, with a gain of 12.1 dBi and its corresponding aperture efficiency is 87.5 to 89.75 percent at 5.8 GHz. Measurement results agree closely with the simulation.
