Abstract :
This paper presents a 140 GHz wide-band double folded slot (DFS) antenna structure. The radiation of the two radiating elements is combined, resulting in a gain of 6.4 dBi at 140 GHz. The structure is designed on a thin dielectric membrane, in order to reduce the dielectric losses as well as the losses due to the surface wave excitation. The antenna gain is greater than 5 dBi between 130-146 GHz, while the reflection losses are lower than -10 dB between 124-164 GHz, resulting in a large fractional bandwidth of ~29%.
