Broadband low cost antennas for wireless application

This paper proposes three-dimensional antennas associating printed technology and that of the metallic waveguides. Radioelectric performances calculated using an electromagnetic simulator, for omnidirectional and directing antennas using a focusing structure, are compared with experimental measurements. Slots antenna supplied with a rectangular waveguides is analyzed and optimized. Compactness and the low cost offered by the association of two technologies allow the developed antennas to be an excellent structure for the wireless broadband communication systems.
