a te _ 01 delta mode omnidirectional dielectric resonator antenna excited by a Special Configuration
IEEE Transactions on Antennas and Propagation, 2018Co-Authors: Hu Yang, Yan He, Junqi LuAbstract:The TE $_{01\delta }$ mode of a dielectric resonator antenna (DRA) is excited by a Special Configuration which is composed of four printed arc-shaped dipoles. Based on this, an omnidirectional cylindrical ring DRA with horizontal polarization is designed, fabricated, and measured. The measured results match well with the simulated ones. The 10 dB return loss bandwidth is 4.5% (2.39–2.50 GHz). Within this operating frequency band, the measured gain is in the range of 2.12–2.54 dBi, and the simulated radiation efficiency is over 87%. Besides, the maximal radiation direction of the antenna is in the horizontal plane and the gain variation in all direction of the azimuthal plane is less than 0.5 dB. Moreover, the designed antenna has a compact size of $0.33\lambda _{0} \times 0.33\lambda _{0} \times 0.10\lambda _{0}$ , where $\lambda _{0}$ is the wavelength of the center frequency.

a Special Configuration of lead zirconate titanate multilayer stack with superior electrical and optical properties
Journal of the American Ceramic Society, 2011Co-Authors: Ting Zhang, Gujin Hu, Haijun Bu, Rui Cong, Xin Chen, G Yu, Xiangjian MengAbstract:A unique Configuration of PbZr0.4Ti0.6O3 multilayer stack was designed and grown on F-doped tin oxide thin film by spin casting and annealing process. The multilayer system exhibits a broad reflection band with peak reflectivity over 95% and band width no < 40 nm, a dielectric constant of 520 and dielectric tunability of ~49% at 1 MHz, a remanent polarization of 46.8 μC/cm2, and a polarization loss of < 5% after 109 polarization switching cycles, rendering excellent performance as 1D photonic crystals and as ferroelectric and dielectric media. This material structure may find application in photonic band-gap engineering, microwave tunable devices, and integrated optoelectronics.
