My name is Yang Wang. I am right now doing researching about antenna and propagation. I am now in Communication Group in Department of Electronic and Electrical Engineering at University of Sheffield, UK.
My research interests are:
1. Phase modulation surfaces
2. Wearable antennas
3. Frequency selective surfaces
4. Active antenna arrays
5. Time modulated arrays
6. Active reflector arrays

Abstract: A new form of RFID tag based on the concept of a phase-modulating surface is presented. The tag consists of a two by two array of pin diode controlled dipole elements. By applying individual d.c. control signals to each of the diodes, it is possible modulate RF energy scattered from the tag. An experimental system is described and measurements made at 10GHz are presented to show that the tag can impart binary phase modulation onto interrogating signals.

Abstract: We introduce a simple radio frequency (RF) tag that can be configured to exhibit direction dependent modulation properties. The tag consists of a two-by-two array of pin diode loaded dipole elements that can be controlled by an external signal to modulate the RF scattering characteristics of the tag. The design of the tag allows for multilevel in-phase and quadrature modulation schemes to be implemented. It is also shown that the form of the modulation generated by the tag is direction dependent and that this property can be exploited to provide an additional degree of system security.

doi: 10.1049/el.2012.1893Abstract: The concept of a time-modulated reflector array (TMRA) is introduced and analysed. The TMRA is proposed as an alternative to conventional time-modulated array designs. The TMRA is potentially much simpler to implement in hardware than the conventional time-modulated array as it does not require a complex feed network. The results of a simple analysis of a TMRA based on an array-factor model combined with Fourier-series theory is presented to illustrate the basic operation of the system and to show that the TMRA exhibits similar characteristics to conventional time-switched arrays. A more realistic TMRA based on pin diode controlled dipole elements is also modelled using a full-wave electromagnetic simulator and the performance of this system is compared to that obtained from array-factor theory.

Abstract：The concept of a time-modulated reflector array is introduced and investigated. A TMRA is proposed as a variant of a conventional time-modulated array. A TMRA is potentially simpler to implement in hardware as it does not require a complex feed structure. A simple 8 element TMRA is analysed using both array-factor theory and full-wave electromagnetic simulation software. The switching sequence applied to the TMRA is configured to produce radiation patterns with low sidelobe levels. The performance of a TMRA consisting of ideal, isotropic elements is compared to that of TMRA consisting of diode controlled dipole elements.
