Deformation Sensitivity Study of Embroidered UHF RFID Antennas
IEEE International Conference on RFID-Technologies and Applications, 2019Textile-based antennas that can be embroidered directly onto cloth fabrics have shown great potential for wearable applications. However, the performance of the embroidered antennas are significantly affected by the materials used, as well as the ...

Design of UHF miniature discone antenna
Proceedings of the 9th International Symposium on Antennas, Propagation and EM Theory, 2010In this paper, a novel miniature discone antenna operated in the ultra-high frequency (UHF) band is presented. The introduction of the back cavity increases the cone angle and reduces the total size. In order to form a back cavity, the bottom of the cone is expanded and bended upward. The size of the discone antenna is reduced effectively.

Body wearable antennas for UHF/VHF
2008 Loughborough Antennas and Propagation Conference, 2008The development of antennas which can be worn on the body is of increasing interest within both the military and civil domain. Body wearable antennas present a considerable design challenge, particularly as most applications require the antenna to be unobtrusive and low-profile.

Proceedings of International Conference on Antenna Theory and Techniques, 1997
The vertically polarized antenna for broadcasting in the UHF range has been developed by the authors. The coaxial resonator with the annular slot in the external cylindrical conductors is the radiating element of the antenna. Characteristic radiator cross sizes account 0.1-0.2 and the width of the slot is no more than 0.02 of a wave-length.

Proceedings 2000 IEEE International Conference on Phased Array Systems and Technology (Cat. No.00TH8510), 2002
This UHF wideband antenna was developed for DARPA's synthetic aperture radar (SAR) applications. The small array could be mounted at the belly of an aircraft. The operating frequency covers a 4:1 bandwidth. The antenna including the feed and a contoured ground plane was designed to fit in a shallow radome (50 cm/spl times/100 cm/spl times/100 cm).

Ultrawideband VHF/UHF dipole array antenna
2010 IEEE International Symposium on Phased Array Systems and Technology, 2010A linearly-polarized ultrawideband dipole array antenna has been developed for coverage in the VHF/UHF frequency range for communications or radar applications. The antenna design utilizes a horizontally polarized array of thick tubular dipole elements above a ground plane.
