A Consistently High Gain Frequency Scanning Antenna for Portable Low-Profile Beamforming Applications Conference Paper uri icon


  • A novel frequency scanning leaky wave antenna with consistently high gain across the entire operating frequency range for portable low-profile beamforming applications is reported. The leaky wave antenna is composed of fifteen unit cells having an overall size of $mathbf{5.15}lambda_{0} imes ext{0.66}lambda_{0} imes mathbf{0.03}lambda_{0}$ at l0GHz. Each unit cell is composed of a SIW structure with a diagonal slot on the top metalized surface that acts as an aperture to feed three square metal rings on top of a superstrate. This structure helps to achieve a uniform gain of higher than 11dBi in the entire operating frequency range that extends from 8 to 12GHz with a continuous beam scanning angle from 60 to 60. The unit cell design and the simulation results of the antenna have been presented in detail.
