“…The simulated gain of the antenna is -6 dBi at 94GHz which is due to the lossy silicon substrate and is typical of bulk silicon on-chip antennas [1]. There are various post-processing techniques that can be adopted to improve the gain, but it increases the cost, complexity and design time [4]. The impedance performance showing a wide bandwidth of 9GHz and omnidirectional radiation pattern of the antenna is also shown in Fig.1 (b and c).…”

A miniaturized 94 GHz oscillator transmitter in 65nm CMOS is presented. An extremely small silicon foot-print of 0.25mm 2 is achieved through meandering of the top-metal dipole antenna, conjugate matching between the oscillator and the antenna without impedance matching elements and efficient placement of the oscillator circuit within the antenna. The antenna demonstrates bandwidth of 90 to 99 GHz (10%) and a gain of -6dBi. The use of parasitic aware antenna-circuit codesign strategy results in an accurate measured oscillation frequency of 94.1 GHz. The oscillator exhibits a measured output power of -25 dBm, phase noise of -88 dBc/Hz at 1 MHz offset and consumes 8.4mW from a 1V supply.

“…DIPOLE ANTENNA At mm-wave frequencies, on-chip antennas become a viable option as the wavelength is comparable to the die size of a complex transceiver design [21], [30]- [33]. Furthermore, on-chip antennas eliminate the loss due to the interconnect techniques such as wire-bond, wafer-level-packaging (WLP), ball-grid-array (BGA), and so on.…”

“…Also, the high permittivity of the silicon substrate results in the absorption of the fields in the substrate thus giving rise to undesirable substrate modes that adversely impacts the antenna efficiency [34], [35]. The two most commonly used techniques to improve antenna efficiency involve using a substrate dielectric lens [30], [36] and substrate thinning [19], [33], [38]. The dielectric lens is large, expensive, and needs accurate placement with respect to the on-chip antenna.…”

A fully integrated 2 2 CMOS transceiver at 60 GHz with energy harvesting capability in the transmitter mode and on-chip dipole antennas is demonstrated. The radio supports on-off-keying (OOK) modulation and a programmable data rate of 38 to 2450 Mb/s at a BER of less than 5 10 . The power consumption of the transmitter scales with data rate from 100 W to 6.3 mW at 5 cm range and from 260 W to 11.9 mW at 10 cm range. This yields an energy efficiency of 2.6 pJ/b at 5 cm and 4.9 pJ/b at 10cm. The energy harvesting circuits operate at 2.45 GHz with an average efficiency of 33%. The harvesting antenna and its matching components are off-chip. The complete transceiver including the energy harvesting block and on-chip antennas occupies 1.62 mm in 40 nm CMOS.Index Terms-Close range, dipole antenna, energy harvest, impulse radio, IR-UWB, low power, MIMO, mmWave, near range, on-chip antenna, OOK, power harvest, 60 GHz, 2 2, ultra wide band.

“…In recent years, while silicon ICs have been shown to generate and radiate THz signals [2], most of the architectures are inherently narrow-band. Digital delay methods and nonlinear lattices to generate broadband pulses are limited by the gate delay and the cut-off frequency of the technology [3]- [5], dispersion due to on-chip antenna, lossy substrates and process variations.…”

In this paper, a scalable architecture is presented which can generate and radiate reconfigurable periodic waveforms in free-space with picosecond time-widths. This is achieved by allowing radiated electromagnetic-fields of fundamental and multiple harmonic frequencies to combine in free-space with the right amplitudes and delays, and quasi-optically construct the time-domain waveform in the desired direction. In this paper, a 4-element array with integrated antennas is presented which is demonstrated to radiate pulse trains of 2.6 ps timewidths as well as pure tones and harmonic frequencies at 107.5 GHz (EIRP=4.5 dBm), 215 GHz (EIRP=5.0 dBm) and any combination of amplitudes and delays of these two harmonics to generate a set of reconfigurable waveforms in free space. No silicon lens or substrate thinning was employed. To the best of the authors' knowledge, this is the sharpest radiated pulses demonstrated in any IC technology. The chip is fabricated in 65nm LP CMOS process.
