Abstract:

The Genetically Optimized Digital Ionospheric Sounding System (DISS) Transmit Antenna is a low-cost modification to the TCI 613F HF communications antenna that increases and stabilizes vertical gain from 4 to 30 MHz. Genetic algorithm and local search techniques were used in the design of the modification in order to take into account both electrical design and mechanical simplicity in this design. The novelty lies in the specific placement of conducting wires with respect to the original TCI antenna. This placement both increases the vertical gain of the antenna as a whole and adds to its stability as each wire also acts as a guy cable.
