The design of electrically small antennas continues to be a challenging effort, primarily due to the tradeoffs involved in reducing antenna electrical size while attempting to maintain some level of acceptable impedance and bandwidth at lower frequencies, especially in HF band applications. Fractal geometries offer a practical solution to these challenges by providing a method for generating complex...
The design of electrically small high-frequency (HF) wire antennas continues to be a challenging effort, primarily due to the tradeoffs involved in reducing antenna electrical size while attempting to maintain some level of acceptable impedance and bandwidth at lower frequencies. There are numerous examples of practical applications where antenna physical dimensions must be restricted. This letter...
The design of electrically small HF antennas continues to be a challenging effort, primarily due to the tradeoffs involved in reducing antenna electrical size while attempting to maintain some level of acceptable impedance and bandwidth at lower frequencies. Current doctrine dictates that optimization can only be achieved when the conductive elements are placed on the surface of the sphere enclosing...
