“…The transmission impairment mechanisms associated with such systems are subsequently addressed. Other and similar characterizations of the transmission mechanisms, interference parameters and bit error analyses were reported (Maalouf et al, 1998), (Purdy & Lier, 2000), (Lier & Maalouf, 2003), (Maalouf & Lier, 2004). Of special interest is the analysis of intermodulation components that result from multicarrier operation of active phased arrays (Sandrin, 1973), (Lier & Charrette, 2005).…”

“…It was based on the modular supertile concept described in [1][2][3][4]. The Ku-band elemental signal is received by four helical antenna elements, followed by waveguide transmission lines, including a 4: 1 combiner and filter, low-noise amplifier, down-converter, beamformer, and gain blocks.…”

“…By deploying the array limitation on power is reduced, since there is no need to dissipate heat off of the thermal radiators of the satellite bus. Also, deployed arrays enable large array apertures, since they are no longer constrained by the Earth deck of the bus [1][2][3][4]. This requires an array design that allows for efficient direct heat dissipation.…”

A 17 GHz receiving multibeam active phased array, based on modular "supertiles," was built and tested. The array was launched and placed in geostationary orbit in 2008. The tile concept is characterized by low volume and low mass, making it well suited for satellite-antenna applications, and in particular for deployed multibeam active phased arrays for communications satellites. The modular design facilitates low recurring cost in a high-volume continuous production. Both component and array measurement data are presented in the paper. Measured array-antenna patterns were in good agreement with estimated and predicted values, proving that the array can be built according to its requirements, and calibrated and controlled to generate independent beams with low sidelobes from low-rms excitation errors.

Driven by the ever‐increasing demand for higher user data rates and greater network capacity, the exploration of the millimeter‐wave (mmWave) spectrum is considered a promising technique in the upcoming fifth‐generation (5G) mobile communication systems. As one of the key components in 5G mmWave systems, antenna designs are facing enormous challenges and therefore attracting much research attention. Several mmWave antenna design parameters gain higher priorities, including bandwidth, gain, polarization, radiation direction, fabrication techniques, and profile, which need further investigation and concern in the design process. Important techniques and research interests are thus discussed in detail, including antenna elements, single‐beam and multibeam arrays, antennas for mobile terminals, and antenna‐in‐package solutions.
