A compact directive dual linear polarized ultra-wideband (UWB) antenna designed for building material analysis (BMA) devices in the frequency range from 2.6 GHz to 4 GHz is proposed. The antenna has a total size of 61 mm2 and a height of 18 mm. The radiation patterns for both polarization directions are symmetrical over a wide bandwidth and radiate perpendicular to the antenna surface. The wave propagation...
An ultra broadband near field probe operating in the frequency range from 2 GHz to 11 GHz was developed. The high bandwidth of the active probe allows to measure the electrical near field of UWB antennas. Due to its small size of 7.6 mm times 56 mm the probe can be set up easily in a near field measurement system and has little effect on the electromagnetic field distribution of the antenna under...
