Transmitter/Receiver Pulse-Driven Antenna Array with Near- Field Beam-Forming for UWB Subsurface Imaging Radar
The paper is devoted to design of impulse or equivalent ultra-wide band array antenna for subsurface radar system. Receiving elements of this antenna are arranged in array with small physical aperture and polarimetric features. Two transmitting element support two polarization states for radiating signals. The radar antenna provides down-looking scanning in subsurface medium for small areas cov...
متن کاملHigh Gain Vivaldi Antenna for Radar and Microwave Imaging Applications
An Ultrawideband (UWB) high gain compact Vivaldi antenna with end fire radiation patterns is presented for radar and microwave imaging applications. The antenna is operating for 2.9GHz to more than 11GHz with -10dB impedance bandwidth and is designed on low cost FR4 substrate of thickness 0.8mm. While designing the proposed antenna, initially a compact exponential tapered slot Vivaldi antenna i...
متن کامل3.51pJ/pulse/1.2V CMOS IR-UWB Transmitter
Spectrum tuning and meeting low power are the main challenges in impulse radio ultra-wideband (IR-UWB) system while it has the highest level of prospects in contactless and continuous vital sign monitoring. In this paper, an IR-UWB transmitter is designed for the most desirable feature of IR-UWB that is exact spectral tuning along with the lowest energy consumption ever reported which is solved...
متن کاملA CMOS 0.18μm 4bits PROGRAMMABLE DELAY CONTROL FOR UWB TIMED ARRAY BEAMFORMING RADAR APPLICATION
We present a Programmable Delay Control (PDC) for UWB Timed Array Radar Application, working with pulses in the GHz region, which requires a precise control of delays in the order of picoseconds. The major component of the PDC consists of a channel formed by two static inverters connected in series. Between the internal transition line (Vlinha) and the ground line (Vss), a digital variable capa...
متن کاملDesign of a Compact Tapered Slot Vivaldi Antenna Array for See Through Concrete Wall UWB Applications
An optimized 1×8 Vivaldi antenna array designed for the lower-band UWB (2-4 GHz) through-wall imaging systems has been developed. Tapered slot antennas were utilized as the array elements and optimized to have a compact size. A one to eight wideband Wilkinson power divider was designed and fabricated to compose the feed network for Vivaldi antenna array. Measured results of the manufactured Viv...
