Frequency-scanning leaky-wave slot antenna array based on serpentine waveguide with open stopband suppression

A periodic leaky-wave antenna with backward-to-forward scanning capability is presented. Two versions of the antenna, one with bidirectional radiation and the other with unidirectional radiation, are introduced. The proposed structure, composed of 30 unit cells, is based on a meandered rectangular w...
