Abstract
Genetic programming (GP) is developed to design an antenna array with new topologies resulting in improved performance. Three elements of a coplanar waveguide continuous transverse stub (CPW-CTS) antenna are synthesized and optimized by GP. These antenna elements are placed in series to create a 3-element frequency scanning linear array. The fitness function used to design the CPW-CTS elements accounts for impedance bandwidth, radiation pattern, cross polarization, and transmission coefficient. Simulation results are verified experimentally. The GP designed CPW-CTS antenna array was able to achieve nearly 4 times the bandwidth of a conventional CPW-CTS array design. The GP designed array maintains the array's gain when compared with the published CPW-CTS antenna array design.
