A Review of Antenna Array Technologies for Point-to-Point and Point-to-Multipoint Wireless Communications at Millimeter-Wave Frequencies

“…e antenna polarization, whether it is linear or circular, can be controlled in rather simple ways. Furthermore, microstrip antennas can conform to the shape of the hosting platform on flat or curved surfaces [27,28]. Patch antennas are particularly suitable for PtM communications, since they feature a radiation pattern with broad coverage that is instrumental to the achievement of wide-angle scanning properties at array level.…”

A Toolbox of Subarrays for Optimizing Wide-Angular Scanning Arrays Using Trade-Offs Between Scan Loss and Side Lobe Level

“…In a linear array with uniform amplitudes and equidistant spacing, a high SLL occurs in wide-angular scanning applications. This high SLL can be suppressed by destroying the periodicity of the inter-element spacing [1]- [33], i.e., by using spatial tapering. From the so-obtained spatial tapering, a virtual specific amplitude tapering can be realized by varying the spacing between successive elements.…”

“…Particular attention was paid to array pattern synthesis by using a deterministic approach [9]- [16], statistic or heuristic approach by natural algorithm [17], mathematical approach [18], [19], as well as quasi brute force method by evaluating all possible combinations [20]- [22]. Synthesis results have subsequently been applied in more recent years to designs of planar and linear arrays [23]- [33].…”

A Design Framework for Beamforming Integrated Circuits Operating at Mm-Wave Frequencies

“…Their operation is based on the superposition principle of electromagnetic waves. In fact, the array radiation pattern is synthesized by feeding the individual antenna elements coherently through suitable phase-shift or time-delay controls at each port so to steer, electronically, the resulting beam in a given direction in space [8]- [11]. This scheme can be further extended to support multiple beams, whereas the implementation of amplitude control at element level can be used to reduce sidelobe level [6], [8].…”

“…The RFFE is based on the same circuitry of the FE with the addition of the up/down conversion stage9 This is estimated for a single 60-GHz chip. For this system to work, a Master-slave needs to be used (with at least two chips), though it can be based on one master for N slaves10 This paper presents the BFIC measurements for different temperatures, the values reported in the table are for 25 • C. For 105 • the circuit presents a NF <12dB, a Psat of 6.5 dBm and a RX P DC /ch of 140 mW11 The paper presents two diffrent chip configurations, with 16TX/8RX and 8TX/16RX12 The paper presents two separate chips, a transmitter with 16 TX channels, and a receiver with 32 RX channels…”
