| What challenges are associated with the CMOS process in chip antenna design, and how does this paper address them? |
The CMOS process poses challenges for chip antenna design, mainly due to the short distance between metal layers leading to lower gain and radiation efficiency, and the silicon substrate causing interference and inefficient antenna radiation propagation. The paper addresses these issues by employing a Vivaldi-like antenna structure. This design reduces losses and improves efficiency. Moreover, the antenna connects Metal 6 and Metal 1 layers to mitigate the detrimental effects of the dielectric constant and resistivity of the substrate on antenna gain. |

| Why does the chip antenna in this paper feature a slot cutting structure? |
The chip antenna incorporates slot cutting in its design to address the limitations imposed by the CMOS process density. Specifically, slot cutting was performed on the Metal 6 layer of the antenna. Slot cutting in the Metal 6 layer is a crucial step to achieve these characteristics while adhering to the process density limitations of the CMOS technology. Simulation testing verified that the slot cutting did not significantly alter the antenna's performance, demonstrating its effectiveness in the design without compromising the antenna's functionality. |
