“…To ensure fabrication consistency validation, each antenna was measured using two samples. For the 11 TE x δ mode on-chip dielectric-resonator antenna, two resonant frequencies were measured, and this was consistent with the simulation depicted in Figure 3. The measured impedance bandwidth was 13% from 126 GHz to 144 GHz.…”

“…Moreover, we propose a half-mode-backed cavityfeeding structure in the on-chip dielectric-resonator-antenna design [11], and apply it to the higher-order-mode dielectricresonator-antenna design to achieve higher antenna gain. With the help of these technologies, the peak gain of the on-chip higher-order dielectric-resonator antenna was measured to be 7.5 dBi at 134 GHz, which is a record for all of the on-chip dielectric-resonator-antenna implementations reported so far.…”

“…The conventional on-chip dielectric-resonator antenna, fed by a cavity backing, which was briefl y introduced in our previous work [11], is extended with a detailed analysis of the cavitybacked feeding structure in Section 2.1. The other kind of antenna, a higher-order-mode dielectric-resonator antenna, which includes two antennas ( 13 TE x δ -mode and 15 TE x δ -mode antennas), is then presented in Section 2.2.…”

In this paper, on-chip higher-order-mode dielectric-resonator antennas (DRAs), fed by a half-mode-backed cavity structure using standard CMOS technology, are presented. With the dominant cavity mode (half-100 z TE ), the half-mode cavity-feeding structure provided a high antenna radiation effi ciency. The dielectric resonators (DRs) were designed to operate at higher-order modes ( 13 x δ TE , 15 x δ TE ) to enhance the antenna gain. At around 135 GHz, the proposed antennas demonstrated measured gains of 6.2 dBi and 7.5 dBi for the 13 x δ TE and 15 x δ TEmodes, respectively, with corresponding simulated radiation effi ciencies of 46% and 42%. Both antennas had a measured impedance bandwidth of 7%. The proposed antennas not only accomplished high gain without occupying a large chip area, but also maintained comparable or even improved cost performance and simplicity over other on-chip antennas.
