A new design technique for an antipodal Vivaldi antenna is presented for developing the ground penetrating radar (GPR) landmine detection system. The newly developed antipodal Vivaldi antenna, which takes a parallel strip-line as its feeding construction, possesses much better properties than the no
## Abstract In this letter, a passive RFID transponder based on an enhancement mode pseudomorphic HEMT (EpHEMT) is proposed. Taking advantage of the slightly positive threshold voltage of this transistor technology, a dualโfunction detector/mixer circuit with good RFโtoโDC and frequency conversion
## Abstract In this letter, a novel broadband dipole antenna for UHF RFID transponder, which offers global functionality across different regulatory areas is proposed. The proposed antenna has a measured bandwidth from 0.83 to 1 GHz (18.5%) where the power reflection coefficient is below โ10 dB for
## Abstract A tapered slot antenna to be used in ultra wideband microwave imaging systems aimed for early breast cancer detection is presented. A synthetic array is designed to operate across the ultra wideband frequency band in the air. The mutual coupling effects between the antennas have been in
## Abstract This paper presents a novel type of waveguide monopulse feeder, which has the concept of a space feed, suitable for liner phased array antenna. The design methods and measurement results of the 2โtoโ39 port feeder at Xโband are described. Measurement results show that this feeder has ch
