This paper discusses different design alternatives for a high gain planar antenna at 240 GHz. The antenna is based on a Fabry-Perot configuration, where two different partial reflection surfaces (PRS) are considered: a free standing metallic plate and a metallized quartz substrate. Similar performance has been found between both alternatives.

A Fabry-Perot cavity antenna with a SiGe on-chip feeder for submm-wave applications
(IEEE, 2024-09-30) Khan, Ihtesham; Herrera-Martín, Juan M.; Urain, Álvaro; Iriarte Galarregui, Juan Carlos; Teniente Vallinas, Jorge; Ederra Urzainqui, Íñigo; Berenguer, Roc; González Posadas, Vicente; Segovia-Vargas, Daniel; Ingeniería Eléctrica, Electrónica y de Comunicación; Ingeniaritza Elektrikoa, Elektronikoa eta Telekomunikazio Ingeniaritza; Institute of Smart Cities - ISC
This paper analyzes the performance of a Fabry-Perot cavity antenna fed by an on-chip spiral antenna and compares it with an on-chip antenna designed to be integrated in IHP's 130nmSiGe BiCMOS chip in a 2 × 2 array configuration. The results show the increase in directivity obtained by the combination of the Fabry-Perot cavity and a single spiral antenna versus the directivity obtained by forming a complex sequentially rotated 2 × 2 spiral array.
