Two-dimensional periodic leaky-wave antenna for oblique frequency scanning [PDF]
, 2022 4 S.A design of two-dimensional (2D) periodic leaky-wave antenna (P-LWA) to achieve an oblique frequency scanning is presented. This property allows for the antenna to independently scan in two distinct planes using opposite ports.
