“…The BER values are less than 10-5 for energy per bit to noise power spectral density (Eb/No) ratio of 10 dB [11]. These results prove that simple multiport architectures can be suitable for low-cost millimeter-wave transceivers for future 60 GHz WLANs.…”

Recommended by Daniel IancuMillimeter-wave multiport transceiver architectures dedicated to 60 GHz UWB short-range communications are proposed in this paper. Multi-port circuits based on 90• hybrid couplers are intensively used for phased antenna array, millimeter-wave modulation and down-conversion, as a low-cost alternative to the conventional architecture. This allows complete integration of circuits including antennas, in planar technology, on the same substrate, improving the overall transceiver performances.

“…This is particularly useful in power combining applications where the use of T junctions decreases return loss values and offers poor isolation between output ports 2 and 3 (as low as 6 dB for both parameters). Feeding networks of millimeter wave antenna arrays benefit from this circular layout, in particular [8,13].…”

“…Nowadays millimeter wave components are requested more and more for very promising applications, such as multi-Gb/s wireless links, radar and imaging sensors. Six-ports have been used for decades in microwave bands and due to their well-known quadrature down-conversion and direct modulation applications; they also play an important role in millimeter wave transceiver implementation [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. There is an increase in the use of microstrip antenna because of its lightweight, low fabrication costs, the capability of supporting multiple frequency bands, and integration with multiple input multiple output (MIMO) [6].…”

The study has presented an extensive analysis of an integrated millimeter wave six-port interferometer, operating over a 10 GHz band, from 80 to 90 GHz. It has covered both semi-unlicensed point-to-point links (81-86 GHz), and imaging sensor system frequencies (above 85 GHz). An in-house process is used to fabricate miniaturized hybrid millimeter wave integrated circuits on a very thin ceramic substrate. Two-port S-parameter measurements are performed on a minimum number of circuits integrated on the same die, exploiting the circuit’s physical symmetry and chosen to collect enough data for full-port characterization. Based on these measurements on an integrated prototype, a six-port circuit computer model implemented and advanced system simulations performed for circuit analysis. Interferometer performances evaluated using several methods: analysis of harmonic balance, qi points’, homodyne quadrature demodulation, and error vector modulation (EVM). The analysis showed that this circuit can directly perform, without any calibration, the demodulation of various PSK and QAM signals over the 10 GHz band, with very good results.

<p> An unambiguous 2-D angle-of-arrival (AoA) estimation receiver (Rx) based on a 16-port interferometer is proposed and demonstrated in this paper<em>.</em> It has three main components: eight antennas, a 16-port interferometer, and a signal processor. The antennas are in the same plane in a concentric-square shaped configuration. The eight input signals are superposed on eight output port signals in the interferometer. First, an AoA estimation algorithm for the proposed 16-port interferometer is described. The algorithm transposes the phase differences between the antenna elements into the power relationship of the output signals. Then, a method for reducing angle ambiguity is introduced. The method allows for the distance between the antenna elements to be larger than λ/2, and the angle detection range is theoretically -90° to 90°. Then, the Rx error models are established to obtain the systematic errors. An Rx operating at 31 GHz was fabricated. The measurements demonstrate that the system operates as expected, with AoAs ranging from 30° to 30° and a mean squared error of approximately 0.4°. </p>
