Abstract :
This paper presents a seven-element dipole circular array with different lengths and separation between the elements that was used to produce maximum gain in certain directions. The method of moments was used to formulate the problem. The radiation characteristics of the array were calculated, considering that one element acts as an active element while the others to act as parasitic elements. The genetic algorithm was used to optimize the dimensions and the separation between the elements
