A compact dual-polarised slot antenna with improved gain is presented in this study. A cross-shaped slot antenna fed by two orthogonal microstrip feed lines is proposed to achieve dual polarisations. A symmetrical feeding structure is employed to realise high isolation between the two ports by utilising a one-to-two divider. The working principles of the slot antenna fed by a fork-like microstrip...
Continuous Transverse Stub (CTS) planar array antenna was firstly invented in early 1990' [1]-[3]. The advantages of this type array include compact format, light weight, low loss and insensitivity to dimensional tolerances accuracy [2]. Besides, the present forms of CTS antenna have wide bandwidth, low dissipative losses compared with the conventional planar antennas. And it has been successfully...
Three-dimensional finite-difference time-domain (FDTD) and pseudospectral time-domain (PSTD) algorithms, with perfectly matched layer absorbing boundary condition, are presented for analysis of the newly designed W-band linear tapered slot antenna on rectangular-grooved silicon substrate. Compared to its ungrooved version, the W-band coplanar-waveguide-fed antenna shows significantly improved endfire...
