Fixed point-to-point microwave links (P-P links) are widely used for vital backhaul connections in cellular networks. One frequency range allocated to P-P links by the International Telecommunications Union ranges from 24.25GHz to 29.5GHz. The same f

In this paper we present a software defined radio (SDR) based measurement framework that allows for simultaneous measurements of wireless communication channels over multiple bands. We present and discuss results of a wireless vehicular-to-infrastruc

A concealed vehicular carbon fiber reinforced polymer cavity in the roof that contains antennas is proposed, prototyped, and measured. Compared to state-of-the-art roof-mounted shark-fin modules, this offers significantly more room for antennas and r

We report on a prototyping platform for antenna design at millimeter wave frequencies with a steerable beam. The antenna beam is formed by a designed aperture in a hollow metallic half-sphere (“shell”) on a circular ground plane which forms a cav

Cavities built into the vehicle chassis have recently emerged as receptacle for hidden antennas. In the automotive sector they potentially replace the roof mounted shark-fin antenna modules. Simulation models for chassis antenna cavities are critical

Chassis cavities have recently been proposed as a new mounting position for vehicular antennas. Cavities can be concealed and potentially offer more space for antennas than shark-fin modules mounted on top of the roof. An antenna cavity for the front
