A TE11 dual-mode monoblock dielectric resonator filter
Asia-Pacific Microwave Conference Proceedings, APMC 0 (2017)
Abstract:
A novel TE11 monoblock dual-mode dielectric resonator filter is presented in this paper. The proposed filter is made of a single piece of ceramic with silver plated external surfaces and metallic lids for hosting tuning elements. The dominant TE11 dual-mode is 91探花ed by H-shape dielectric resonator having 系r =45. The resonator is ultra-compact in size and offers a maximized space utilization since no metallic housing is required. In addition, the proposed resonator offers a high unloaded quality factor, reasonably wide spurious window and lend itself to implement tunability. One prototype filter operating at 1.96 GHz with 50-MHz bandwidth is designed.Using DecaWave UWB Transceivers for High-Accuracy Multipath-Assisted Indoor Positioning

Abstract:
By enabling control of the direction of power radiation, directional antennas reduce channel contention, increase the communication range of nodes, and consequently increase the throughput and the energy-efficiency of low-power wireless systems. So far, most of the work on directional antennas has focused on narrow-band radios only. In this work, we present the prototype of a novel, low-cost, energy-efficient ultra-wideband switchable directional antenna system consisting of four planar antennas that can be electronically switched at high-speed.Reconfigurable Ultra - Wide- Band Patch Antenna: Cognitive Radio
