Abstract :
The leaky coaxial cable (LCX) with vertical periodic slots is considered as an antenna array. By superposition principle, the field distributions of the LCX both in radial and axis directions are analyzed, the radiation patterns for near and far regions of the cable are studied. The relationships between the field distributions and the radiation modes are discussed. In addition, the field distribution and fluctuation of a discrete antenna system are also studied in terms of the theory of LCX for comparison.
