The leaky cables, such as the leaky coaxial cable and leaky circular waveguide, are capable of distributing much smoother radio wave coverage than the discrete antenna system. However, when the leaky cables are used in the urban mass transit, they might be influenced by the extremely bad weather, especially for the low temperature and accumulated snow. In this paper, the influences of snow coverage...
Transmission loss of the leaky coaxial cable (LCX) is increasing with the operating frequency. In order to avoid the large transmission attenuation of LCX at higher frequency, the proposition of replacing the coaxial cable with circular waveguide to construct leaky waveguide is put forward in this letter. The spatial harmonics and their radiation conditions of the proposed dielectric-filled leaky...
Transmission loss of the leaky coaxial cable (LCX) increases with operating frequency. In order to reduce the transmission loss, circular waveguide is used to replace the coaxial cable in microwave band. Similarly, to reduce the transmission loss of the leaky wave structure, leaky circular waveguide is used. However, due to rotating symmetry, the polarization plane of the dominant mode TE11 in circular...
