Series-Fed Printed-Dipoles With a Director for Substrate Lateral Radiation

The use of the 300 GHz band is considered for next-generation wireless communication. Considering the integration of the RF front end and the antenna, it is preferable to integrate the antenna on the substrate. A series-fed printed-dipole with a director is presented in this paper. An antenna that radiates in the lateral direction of the substrate was designed by simulation. The relative frequency bandwidth was 41% for the reflection coefficient below -10 dB. A maximum gain of 7.5 dBi was obtained in the lateral direction of the substrate.
