Multiple beams switching double square loop antenna or UWB Systems

A novel method of producing multiple axial and tilted beams using eight feed double square loop (DSL) antenna is proposed. With varying permittivity value of dielectric substrate, the DSL antenna produces multiple beams and steer each of the beam produced at step of 45º throughout the 360º of space, thus offering wide range of option for any modern wireless device integrated with this antenna to focus the beam in target direction. Also the antenna operates in four different frequencies providing multi-channel operation in UWB region.
