Multiple beams scanning eight feed double square loop antenna for UWB communications

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 45° throughout the 360° 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.
