Abstract-A novel characterization method of OTA test setups for wireless communication systems on vehicles in the random line-of-sight (Random-LOS) environment is proposed. The measurement setup assumes a compact range and a test zone where the antenna under test (AUT) on the vehicle would be located. An ideal receiver is assumed for the reference measurement, which allows to perform a system analysis through evaluating the Probability of Detection (PoD) as the system figure-of-merit. The proposed method is aimed as an aid for test equipment designers to design OTA compact ranges, compare their performances, and define an ideal numerical reference. The requirements for OTA measurement ranges are different from those for conventional anechoic compact ranges. A compact cylindrical reflector system with an antenna array line feed is characterized using the proposed method, from 1.6-2.7 GHz, for two orthogonal polarizations, various AUT heights and reflector tilting angles, with and without ground plane in a test zone which is 2 m wide in diameter.

“…1(b)]. The effects of ground plane and mechanical tilt of the reflector, which were not studied before, are now taken into account [27]. Furthermore, more realistic bowtie antenna elements (optimized for 1.6-2.7 GHz) are assumed for the array feed [28,29], as opposed to those assumed in [27,30].…”

“…The state-of-the-art on OTA testing for vehicles can be found for testing methodology verification [7]- [12] and vehicular channel models [12]- [15], respectively. In [7], an experiment with a car under a multi-probe setup in an open area was performed, and it was found the coupling from the OTA probes and the reflection and diffraction from cars are negligible, which verified the effectiveness of the quiet zone of the multi-probe setup for car testing.…”

“…In [10], throughput measurements for cars were performed in a semi-anechoic chamber, where the ground was not covered by absorber, with a single OTA probe under single-path line-of-sight (LoS) channels. In [11], a plane-wave generator (PWG) solution was reported as an alternative for the compact antenna test range (CATR) setup [12] under single-path LoS channels. In [13], discussion was given on the properties of vehicular channels, and measurement-based path loss and shadowing models were proposed for vehicle-to-vehicle (V2V) communication in highway and urban scenarios in [14], [15].…”

In this paper, we propose a linear array configuration for Random Line-of-Sight Over-The-Air testing set-up in anechoic chamber. For this aim, we use the selfgrounded dual-polarized bowtie antenna as the element in the array. We present a new design of the bowtie to improve the array performance in terms of reflection coefficient and directivity. The new design has a simpler profile to manufacture. A good reflection coefficient performance has been achieved over the entire band of interest, i.e., 1.6-3GHz. The directivity of the array is almost constant for both polarizations over the entire frequency band.
