Abstract :
A broadband waveguide-fed slot antenna is firstly presented. This antenna is then associated with a focusing structure (dielectric lens) in order to improve the performance in the K band. A low cost and broadband antenna with 18 dBi measured gain is obtained and is therefore suitable to many commercial millimeter-wave systems.
