Abstract

This paper presents a study on non-invasive radiation pattern characterisations of an ultra-wideband (UWB) antenna for integration into an antenna-on-vehicle platform for collision avoidance applications. The UWB antenna under test (AUT) is designed to operate between 3.5 and 10 GHz. A comparison was made between its radiation profiles at 6.49 GHz while standalone, with a metallic housing and with a pseudo-real vehicle ground platform. All measurements are made in an anechoic chamber. A non-invasive opto-electric field sensor system was employed to minimize distortion of the antenna pattern. The results show that the problem of minimising the effects towards antenna radiation pattern due to proximity effects and vehicle platform is far from trivial.
