Abstract/Summary:
Integrated circuits, ICs, and printed circuit boards, PCBs, need to be designed optimally to complement each other for system level functionality. This is critical in radio frequencies where inductors and antennas are essential to the system. For inductor design, PCB is better over silicon as it delivers higher inductance and quality factor for given cost/area. PCB also provides the ability to design high gain antennas. This thesis proposes a design flow from inductors to antennas for students in system design. The flow includes theory, design, simulations as well as fabrication and measurements. The goal is to characterize a PCB substrate through two inductors to optimize simulators for a GPS L1 antenna design. For intermediate frequency applications, the larger inductor at 200MHz has measured inductance of 95nH, resistance of 2.9O, and quality factor of 51. The antenna has a measured bandwidth of 250MHz and a return loss of |-36|dB at 1.5754GHz.
