The antenna of ground penetrating radar (GPR) used for the exploration such as buried objects under rubble at the time of disaster is required to have small size and wideband characteristics. A folded ...

Wide band cross bow tie (CBT) antenna with circular polarization (CP) and good gain operating at X band has been presented for satellite communication. Impedance transition from imbalanced 50 ohms to ...

This paper presents millimeter-wave and terahertz double bow-tie slot antennas on a synthesized elliptical silicon lens. Two different antennas are designed to cover 0.1-0.3 and 0.2-0.6 THz, ...
