The antenna is printed on the bottom of a dielectric superstrate with a ground plane below. The new design provides high bandwidth and high efficiency. Two different examples of the new concept have been designed and manufactured for the 60 GHz industrial scientific medical (ISM) band using folded dipoles. Simulated and measured input impedance matching and far field radiation patterns for both antennas will be shown and discussed. Both designs achieve over 10% bandwidth while maintaining better than 80% efficiency. Index Terms—Millimeter wave (mmWave) antenna, planar dipole, superstrate antenna.

The principal application envisioned is in high-speed 60-GHz wireless networks, but the concepts may be applicable to other products as well, such as 77-GHz radar sensors. Circuit results are presented for both 60 and 77 GHz, including an LNA, a highly-integrated direct downconverter, a mixer for a superheterodyne receiver, and a power amplifier. Packaging issues which arise at millimeter-wave frequencies are discussed, and a packaging approach involving a Si IC and a planar antenna in the same package is described. Measurement results for a planar Vivaldi antenna are presented as an example.

A CMOS–based application specific integrated circuit (ASIC) fabricated in 14nm FinFET technology was used to generate and sequence qubit control waveforms and demonstrate a two–qubit cross resonance gate between fixed frequency transmons. The controller was thermally anchored to the T = 4K stage of a dilution refrigerator and the measured power was 23 mW per qubit under active control. The chip generated single–side banded output frequencies between 4.5 and 5.5 GHz with a maximum power output of -18 dBm. Randomized benchmarking (RB) experiments revealed an average number of 1.71 instructions per Clifford (IPC) for single–qubit gates, and 17.51 IPC for two–qubit gates. A single–qubit error per gate of є1Q=8e-4 and two–qubit error per gate of є2Q=1.4e-2 is shown. A drive–induced Z–rotation is observed by way of a rotary echo experiment; this observation is consis...

We took a single-carrier approach with a usual DQPSK modulation scheme, assuming an LOS environment, and implemented the system with FPGAs. At the same time, in order to take care of more frequent sync/burst errors in high-data-rate single-carrier approaches, we equipped the baseband with effi- cient random/packet error recovery and symbol-timing recovery with an effective interpolation method. As a result, a clear and crisp image was obtained in the end-to-end transmission. I. INTRODUCTION

By slotting the vertical ground plane close to the radiator of the antenna and modifying the feeding structure, a low-profile antenna is capable of providing well-matched bandwidth and accepted gain over UWB band. The design is validated by measurement in terms of impedance bandwidth, radiation patterns and gain. 1.
