“…The biggest challenge encountered by PAFR is the limitation of illumination area, that is, only limited array elements can be located in the area of maximum power density, which results in a limited EIRP level and the beam-scanning capability. As reported in [ 24 ], by increasing the axial displacement, a higher EIRP can be achieved in the PAFR antenna. For the mentioned 9 × 9 array fed reflector system working at 71 GHz, an axial displacement of 2.3

towards the reflector could provide an EIRP increase of 8 dB.…”

Long-range E-band communication with fiber-equivalent speed is emerging extensively as a critical technology in the next-generation communication. This paper firstly reviews the relevant progress in recent research. A brief survey is presented on high-speed, long-range E-band communication systems and their relevant techniques that are essential to the link design, including antenna, power amplifier (PA), channel, and digital baseband processing. In the second part, we review our recent field trial of a long-range air-to-ground E-band link, which maintains steady transmission from a slow-moving helium balloon to the ground station with a vertical dimension of 20 km. The improvement directions and future research topics are then discussed.

“…However, with fewer elements active, the transmit power is also reduced. It is possible to intentionally increase the number of active antenna elements of an FPA by shaping the reflector or subreflector [12] [13], or by axially displacing the array [14], increasing the EIRP. Regardless of this design choice, to achieve wide angle scanning it is still needed to populate the full focal plane also resulting in an expensive system.…”

A new antenna system concept is presented where a wide-scan focal plane array antenna is used to achieve point-to-multipoint communication. The focal plane of a parabolic toroid reflector is populated with several antenna arrays, the positions of which determine the directions of the beams. This concept is investigated for beams pointed towards 0 • (broadside) and 28 • in azimuth. Each array allows for scanning an additional ±1 • in azimuth and elevation. This allows for compensation of twist and sway of the antenna mast. Several array configurations are compared in terms of directivity and scan loss for such a system at E-band. It is found that an 8-by-8 array with an inter-element spacing of 0.7λ0 results in an optimal directivity with a scan loss lower than 1dB when scanning ±1 • in azimuth and elevation. For the 0 • beam direction the directivity is 45.5dBi and for the 28 • beam direction the directivity is 44.4dBi, showing the wide angle scanning properties of this system. An experimental system is built at K-band and measurements are performed showing this system in action. In the measurements an array of 8-by-8 is used with an inter-element spacing of 0.5λ0. The scan loss when scanning ±2 • in azimuth and elevation is below 1dB. The directivity is 37.0dBi and 35.4dBi for the 0 • and 28 • beam directions, respectively. The spillover losses and aperture efficiencies are also found, as well as a relative metric for the transmitted power and the effective isotropic radiated power for both the E-band and K-band systems.

“…Over the years, specific applications that use mm-wave frequencies have emerged. These applications include car radar [1], car-to-car communication [2] using on-chip antenna arrays [3], [4], and point-to-point [5], [6] and short-range communication, such as the wireless connector [7]. Each application demands a specific antenna, varying from a low-gain single element to a high-gain large antenna array.…”
