Abstract:
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 5.15λ 0 ×0.66λ 0 ×0.03λ 0 at 10GHz. 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.
