Massive antenna array for space-time channel sounding

In this paper, a prototype of a dual-polarized array antenna is presented. This array was designed in the framework of a collaborative project on spatial modulation schemes. It will be used for the project testbed and for space-time channel measurements. This array features several novelties, including a slant uniform planar structure, a scalable design with integrated switching circuitry, a reference antenna and a camera. The array has been successfully used with a wideband channel sounder to provide real-time radio photos.
