• - For the measurement process, the chip antenna was placed on a platform within the signal source system, surrounded by absorbing material, and connected via GSG probes. As shown in Figure 7, the simulation results reveal that the chip antenna resonates at two frequencies, 141 GHz and 180 GHz. The simulated bandwidth of the antenna is 43.2%, covering a frequency range from 124 GHz to 192.4 GHz. In contrast, the measured bandwidth is slightly narrower at 36.5%, spanning from 140 GHz to 202.5 GHz. Due to the limitations of the measuring instrument, which can only assess frequencies between 140 and 220 GHz, it wasn't possible to obtain measurement results below 140 GHz. However, extrapolating from the measurement trends observed between 140 and 220 GHz, it's inferred that the performance below 140 GHz would likely align with the simulation results. |
