“…However, these connections become increasingly challenging at higher frequencies. For example, the use of a probe can influence the measured results of ESAs [18], [19], and for many IAs, it is not possible to separately connect the antenna, since the AUT is integrated in a full system and the AUT may be difficult to reach. Therefore, a method which can estimate antenna efficiency contactlessly is necessary for the characterization of ESAs and IAs.…”

“…Wafer probes have to be used to contact and feed integrated antennas [1]. These probes are primarily made from metal and thus present a comparably big reflective surface in the immediate vicinity of the AUT [2]. The reflections from the wafer probe cause ripples in the radiation pattern and large deviations in gain measurements that depend on the measurement distance and the relative positions of reflector and antenna.…”

“…In [2] the probe is moved underneath the measurement surface in order to reduce reflections and distortions by bending the printed circuit board (PCB). While reducing reflections significantly at 60 GHz, this approach is not applicable for on-chip antennas as the substrate is way smaller than a PCB and cannot be bent.…”

Abstract-In this paper the results of integrated antenna measurements are analyzed to identify the main reflection locations when measuring with wafer probes. Two different approaches are described and the measurement results for two different probe designs are shown. First, the main reflection center on the wafer probe is determined by analyzing the measured far field radiation pattern at 160 GHz. The second approach is based on an extrapolation measurement of the antenna. It is shown that the reflective areas can be identified for both probe designs. The results can be used to assess the measurement uncertainty and to quantify the measurement error.

“…A good agreement between simulated and measured results is achieved. The simulation model includes the GSG measurement probe as well as the mount for the antenna under test, as their influence on the measured radiation pattern is not negligible at mmWave [40]- [41]. As such, all parasitic radiation and reflections are included in the simulation and the experimental setup is approximated as close as possible.…”

Abstract-A novel wideband substrate integrated waveguide (SIW) antenna topology, consisting of coupled half-mode and quarter-mode SIW resonant cavities, is proposed for operation in the 60 GHz band. This innovative topology combines a considerable bandwidth enhancement and a low form factor with compatibility with low-cost PCB manufacturing processes, making it excellently suited for next generation, high data rate wireless applications. Moreover, exploiting SIW technology, a high antenna-platform isolation is obtained, enabling dense integration with active electronics without harmful coupling. The computer-aided design process yields an antenna that covers the entire [57-64] GHz IEEE 802.11ad band with a measured fractional impedance bandwidth of 11.7% (7 GHz). The measured maximum gain and radiation efficiency of the prototype are larger than 5.1 dBi and 65%, respectively, within the entire impedance bandwidth.Index Terms-Coupled resonators, substrate integrated waveguide (SIW) antenna, half-mode SIW (HMSIW), quartermode SIW (QMSIW), bandwidth enhancement, wideband, 60 GHz. I. INTRODUCTIONn recent years, an increasing demand for broadband multimedia applications has appeared, which forces the capacity of wireless networks to increase continuously. 5G mobile communication is an excellent example of this trend, as extremely high data rates need to be offered to the end user. To this end, novel wideband antenna topologies need to be developed, exhibiting a limited footprint while being implemented through cost-efficient manufacturing, as required for integration into user equipment, such as handsets.As the spectrum up to 6 GHz is becoming ever more crowded, the [57-64] GHz IEEE 802.11ad band is the ideal candidate to meet the requirements of 5G mobile communication systems, both in terms of bandwidth and number of interconnected devices.

He is currently an FWO unlicensed band offers 7 GHz of frequency spectrum for wideband communication. The high atmospheric attenuation, caused by the absorption peak of oxygen atoms, makes the conditions ideal for short range, low interference, and highly secure communication between many devices sharing the same spectrum [1]- [2].Nowadays, a breakthrough of the very promising Substrate Integrated Waveguide (SIW) technology is apparent in the millimeter wave research field [3]. Recent trends and applications include antennas, filters and couplers for RF frontends [4], beam steering [5] and MIMO systems [6]. The heightened interest in SIW technology for millimeter wave applications can be att...
