Abstract :
In this work we investigate a slot bow-tie antenna fabricated using wet-etching technique on a 5mil laminate having a low dielectric constant (εr = 2.2). The planer antenna is aiming to operate, linearly polarized, in the range of 85–95 GHz. The return-loss measurements show acceptable agreement with FEM simulations. The simulated radiation patterns and Co/Cross polar patterns are also presented.
