A new ultra-wideband antenna for UWB applications

Microwave and Optical Technology Letters, 2004
AbstractIn this paper, we propose a new ultra‐wideband (UWB) antenna for UWB applications. The proposed antenna is designed to operate from 3.2 to 12 GHz. It consists of a rectangular patch with two steps, a single slot on the patch, and a partial ground plane.

Code-Shifted Reference Ultra-Wideband (UWB) Radio

6th Annual Communication Networks and Services Research Conference (cnsr 2008), 2008
In this paper, a code-shifted reference ultra-wideband (CSR-UWB) transceiver, which separates the reference pulse sequence and the data pulse sequences with a set of shifting and detection codes selected from Walsh codes, has been proposed to remove the ultra wideband delay element required by the transmitted reference UWB transceiver.

A novel ultra-wideband (UWB) pulse transmitting scheme

IEEE 60th Vehicular Technology Conference, 2004. VTC2004-Fall. 2004, 2005
A novel pulse transmitting scheme is proposed based on the integration of RF modulators into a resonant antenna. Driven by the modulating signals, the modulators are able to modulate on the antenna radiation slots directly. Therefore narrow pulse sequences can be generated and radiated out simultaneously. Furthermore.

Ultra Wideband (UWB) Interference on UMTS Receivers

2007 2nd International Symposium on Wireless Pervasive Computing, 2007
This paper discusses the effects of impulse radio ultra wideband (UWB) interference on narrowband radio systems. It presents the fundamental mathematical modeling of the interaction between the UWB signal and the narrowband victim receiver. Further, as an example, it demonstrates the effects of UWB interference on a UMTS receiver through simulations ...

Design of ultra-wideband (UWB) MIMO antenna

2017 International Conference on Intelligent Computing and Control (I2C2), 2017
In this paper design of ultra-wideband (UWB) multiple-input multiple-output (MIMO) antenna with wideband operation from 2.83 GHz to 10.18 GHz is presented. The designed antenna is combination of two similar patch antenna, which can operate in wideband. Isolation among both patches is obtained by inserting two parallel strips in between them.
