[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - Miniaturized Switchless Pattern Reconfigurable Antenna Utilizing Spherical Modes Analysis
摘要： The paper proposes an electrically small pattern reconfigurable antenna, which allows flexible beamforming with the antenna diameter being λ/5. The antenna has 3 ports, each designed to radiate a different spherical mode. By applying appropriate phase shift the antenna allows to flexibly sweep its bi-directional radiation pattern across a 360° azimuth, while offering 5 dBi directivity.

[IEEE 2018 IEEE Conference on Antenna Measurements & Applications (CAMA) - Va?ster?s (2018.9.3-2018.9.6)] 2018 IEEE Conference on Antenna Measurements & Applications (CAMA) - CPW fed Antenna for Nearfield Sensor Applications
摘要： An Electrically Small antenna with narrow bandwidth suitable for nearfield sensor application is presented. The operation principle is based on a Distributed Reactive Nearfield Parasitic Element (DRNPE). The DRNPE unit cell with high distributed inductive reactance is introduced near a highly capacitive open ended CPW transmission line, provides a high impedance matching. The resonant frequency is independent of the transmission line parameters and hence can be tuned with respect to the DRNPE parameters. The prototype used as a sensor for the measurement of dielectric constant variation is also discussed. The simulation is carried out using Ansoft HFSS and measurement using HP8510C Vector Network Analyzer.
