Performance of a novel differentially-fed UWB antenna operating at 60 GHz frequency range and manufactured in the LTCC technology is analysed theoretically. The antenna is based on aperture stacked patch fed via an H-shaped slot and is fed by a parallel transmission line which enables the antenna to be directly integrated with differential RF MMICs. Influence of the substrate size has been investigated.
In this paper, a comprehensive analysis of a novel GPR antenna featuring almost 30 : 1 relative bandwidth (55 MHz - >1.5GHz), with a maximum antenna size of 40 cm is performed. The antenna transient behavior, near-field radiation properties, and the impact of the ground are analyzed in details. It has been shown that the antenna exhibits reduced and short ringing, low spurious energy emission in...
Within ORFEUS (Optimized Radar for Finding Every Utility in the Street) project a novel antenna system for a SFCW GPR has been developed for detection and location of buried utilities. The antenna system consists of two cavity-backed resistively loaded bow ties and has been designed to cover the frequency range from 100 MHz to 1 GHz with a reasonably high radiation efficiency. The characteristics...
