In this paper, the performances of the neural-network approach for discrimination of the landmine depth from the ground surface and the landmine radius are carried out. A sensor for landmines detection consists of two microstrip antennas is used. One of the antennas is used as transmitting antenna and the second is considered as receiving antenna. Circular cylindrical shape metallic landmine is used...

Chirp pulse microwave computed tomography (CP-MCT) was developed for visualization of permittivity distribution inside a human body (Miyakawa, 1993 and Bertero et al., 2000). Tissue characterization using one of the developed CP-MCT systems has been attempted to discriminate tumor tissues from the normal ones. Based on the dependence of temperature, sugar content, acid content and the other quantities...
MIMO (multiple-input multiple-output) systems have been widely used in the new generation mobile communications because of their large capability, high speed and low code errors. Transmitting and receiving antenna systems are the very important parts of the whole systems. And their designs will directly affect MIMO system's performance. In this paper, a type of printed-dipole antennas is introduced...
In this paper, the transmitting and receiving characteristics of a printed UWB antenna are studied. A pair of CPW-fed disk monopole antenna was fabricated and the transfer function of antenna system was measured. Based on the transfer function and the reciprocity theorem, transmitting and receiving characteristics of the CPW-fed disk monopole are calculated. Furthermore, radiated pulse is obtained...
