Ultra-Wideband 3-D Microwave Absorbers With Composite Slotlines and Microstrip Lines: Synthetic Design and Implementation

The Design and Implementation of Ultra- wideband Microwave Amplifier

Equivalent gain amplification and broadband networks matching of weak microwave signal are difficult in Ultra-wideband microwave receiver system. A highly integrated amplifier IC ADL5541 from ADI is adopted as the core unit in this paper, coordinate with an external matching network. The design can realize an Ultrawideband microwave amplifier with 15dB gain which works in the 500~4000MHz with +...

Design and Fabrication of Ultra Wideband Microstrip Antenna for Ultra Wideband Applications

All Rights Reserved © 2016 IJARECE 2335 Abstract— In this paper, an Ultra Wideband antenna for UWB applications and a coplanar Waveguide Feed is presented. The size of the antenna is 25 mm x 25 mm x 1.6 mm 3 and it is prototyped on FR-4 epoxy substrate material which has a dielectric constant of 4.4 at a frequency of 3.03 GHz. The proposed antenna provides a bandwidth of 11.36 GHz from 10.44 GH...

Design and Implementation of Microwave Dual-Band Bandpass Filters Using Microstrip Composite Resonators

In this paper, a novel type of dual-band bandpass filter (DBBPF) is proposed by using microstrip composite resonators, and its design method is developed based on the lumped-element equivalent circuit of the filter. Both the midband frequencies and the passband widths of the dual bands of the filter can be controlled separately. Four DBBPFs with different specifications are designed, fabricated...

Radar Sensing Using Ultra Wideband – Design and Implementation

Ultra-wideband (UWB) has received significant attention for applications in target positioning and wireless communications recently. The extremely short pulses in turn generate a very wide bandwidth and offer several advantages, such as large throughput, covertness, robustness to jamming, lower power, and coexistence with current radio services. UWB not only can transmit a huge amount of data o...
