Additive manufacturing (AM) of passive microwave components is of high interest for the cost-effective and rapid prototyping or manufacture of devices with complex geometries. Here, we pre-sent an experimental study on the properties of recently demonstrated microwave resonator cavities manufactured by AM, in view of their applications to high-performance compact atomic clocks. The microwave...

Design of atomic clock cavity based on a loop-gap geometry and modified boundary conditions

Ivanov, Anton E ; Affolderbach, Christoph ; Mileti, Gaetano ; Skrivervik, Anja K

In: International Journal of Microwave and Wireless Technologies, 2017, vol. 9, no. 7, p. 1373-1386

In this study, we investigate a concept that can be used to improve the magnetic field homogeneity in a microwave cavity applied in a novel, high-performance atomic frequency standard. We show that by modifying the boundary conditions in the case of a loop-gap geometry, a good improvement of the field homogeneity can be obtained. Such a design demonstrates high potential to improve the frequency...

Compact High-Performance Continuous-Wave Double-Resonance Rubidium Standard with 1.4 × 10−13 τ −1/2 Stability

Bandi, Thejesh ; Affolderbach, Christoph ; Stefanucci, Camillo ; Merli, Francesco ; Skrivervik, Anja K ; Mileti, Gaetano

In: IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2014, vol. 61, no. 11, p. 1769-1778

We present our studies on a compact high-performance continuous wave (CW) double-resonance (DR) rubidium frequency standard in view of future portable applications. Our clock exhibits a short-term stability of 1.4 × 10−13 τ −1/2, consistent with the short-term noise budget for an optimized DR signal. The metrological studies on the medium- to longterm stability...

The Microloop-Gap Resonator: A Novel Miniaturized Microwave Cavity for Double-Resonance Rubidium Atomic Clocks

Violetti, Maddalena ; Pellaton, Matthieu ; Affolderbach, Christoph ; Merli, Francesco ; Zürcher, Jean-François ; Mileti, Gaetano ; Skrivervik, Anja K

In: IEEE Sensors Journal, 2014, vol. 14, no. 9, p. 3193-3200

Nowadays mobile and battery-powered applications push the need for radically miniaturized and low-power frequency standards that surpass the stability achievable with quartz oscillators. For the miniaturization of double-resonance rubidium (87Rb) atomic clocks, the size reduction of the microwave cavity or resonator (MWR) to well below the wavelength of the atomic transition (6.835 GHz...

New Miniaturized Microwave Cavity for Rubidium Atomic Clocks

Violetti, Maddalena ; Merli, Francesco ; Zürcher, Jean-François ; Skrivervik, Anja K. ; Pellaton, Matthieu ; Affolderbach, Christoph ; Mileti, Gaetano

In: Proceedings of the IEEE-SENSORS-2012, 2012, p. 315-318

Nowadays there is an increasing need for radically miniaturized and low-power atomic frequency standards, for use in mobile and battery-powered applications. For the miniaturization of double-resonance (DR) Rubidium (87Rb) atomic clocks, the size reduction of the microwave cavity or resonator (MWR) to well below the wavelength of the atomic transition (6.835 GHz for 87Rb)...

Compact microwave cavity for high performance rubidium frequency standards

Stefanucci, Camillo ; Bandi Nagabhushan, Thejesh ; Merli, Francesco ; Pellaton, Matthieu ; Affolderbach, Christoph ; Mileti, Gaetano ; Skrivervik, Anja K.

In: Review of Scientific Instruments, 2012/83/10/104706-1/8

The design, realization, and characterization of a compact magnetron-type microwave cavity operating with a TE011-like mode are presented. The resonator works at the rubidium hyperfine ground-state frequency (i.e., 6.835 GHz) by accommodating a glass cell of 25 mm diameter containing rubidium vapor. Its design analysis demonstrates the limitation of the loop-gap resonator lumped model...

Integrated solar panel antennas

Vaccaro, S. ; Torres, P. ; Mosig, J. R. ; Shah, Arvind ; Zürcher,, J.-F. ; Skrivervik, A. K. ; Gardiol, F. ; de Maagt, P. ; Gerlach, L.

In: Electronics Letters, 2000, vol. 36, no. 5, p. 390-391

A new antenna which combines solar cells and printed patches is presented. The antenna is designed so as to accommodate the solar cells that provide power to an MMIC amplifier. A 2×4 array is presented, which operates at the frequency of 3.76 GHz and has a bandwidth of 16% and gain up to 30 dBi (active).
