Bowers and Hajimiri Win Best Student Paper at IMS 2013
June 6, 2013, Seattle, WA
The paper titled: “An Integrated Multi-Port Driven Radiating Source” by graduate student Steven M. Bowers and Professor Ali Hajimiri receives the best student paper award at the 2013 International Microwave Symposium (IMS). It presents a holistically designed, fully integrated, mm-wave radiator that operates at 160 GHz with applications in biomedical imaging, security, and communications. The radiator utilizes the integrated nature of modern silicon processes to enable a unilaterally driven multi-port antenna that produces a traveling current wave around a ring.
An 8-phase ring oscillator and amplifier chain were designed in close concert with the antenna, which provides 8-way power combining, impedance matching, and power transfer off-chip through a single structure, drastically reducing losses incurred when these functions are designed separately. The radiator, implemented in a 130nm SiGe BiCMOS process, produces a maximum 4.6 dBm effective isotropically radiated power (EIRP) with a total radiated power of 0.63 mW at 160 GHz. Chip was fabricated by ST Microelectronics.
