Research on Ultra-Wideband Antenna

2008 4th International Conference on Wireless Communications, Networking and Mobile Computing, 2008
This paper introduces the character and requirement of UWB antenna based on microstrip quasi-horn, horn, abnormity monopole, microstrip meandered-loop and biconcial omni-directional antenna. Several types of antenna for UWB are reviewed. These antennas are simulated and compared. These improvements are provided.

Ultra-wideband antenna arrays

IEEE Antennas and Propagation Society International Symposium. 2001 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.01CH37229), 2002
The radiation characteristics of ultra-wideband (UWB) monopulse arrays are discussed in this paper. The UWB arrays considered here consist of ultra-wideband sources radiating coded sequences of ultra-narrow Gaussian mono-pulses with very low duty cycle.

An ultra-wideband reflector antenna

Proceedings of IEEE Antennas and Propagation Society International Symposium, 2002
An experimental reflector antenna using a hybrid orthogonal TEM (transverse electromagnetic) feed concept is described. The new TEM feeding arrangement extends the operating frequency bandwidth by allowing the reflector antenna to operate efficiently at lower frequencies. The radiation characteristics were examined over a 10:1 bandwidth.

A novel ultra-wideband antenna

Antennas and Propagation Society Symposium 1991 Digest, 2002
The authors present a novel ultra-wideband antenna that has been developed by combining two radiating structures, the slotline antenna and the bowtie horn antenna. It is shown that this antenna can maintain a stable pattern throughout a wide bandwidth, in this case 2 to 18 GHz, a flat plateau-like main beam, low sidelobes, low voltage standing wave ...

Antennas for ultra-wideband systems

2017
Wide-band wireless systems are used in a wide range of applications including ground-penetrating radars, biomedical imaging systems, high-data-rate short range wireless local networks, communication systems and medium- and long-range military radars due to their high spatial and temporal resolution. As is the case in conventional wireless communication
