[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) - Reconfigurable Half-Mode Substrate-Integrated Cavity Antenna Arrays
摘要： A frequency-recon?gurable array of HMSIW cavity antennas is presented in this paper. The tuning of the frequency is controlled using stub-loaded varactors. The feeding network can be designed so that the antenna either operates with omni-directional or broadside patterns. Two antenna arrays have been designed demonstrating a frequency tuning range of about 27% from 3.05 GHz to 4.0 GHz. The overall simulated ef?ciency, including the feeding network, is better than 56% for the omni-directional antenna and 42% for the broadside antenna.

A NOVEL DUAL-BAND SIW FILTER WITH HIGH SELECTIVITY
摘要： A novel dual-band substrate integrated waveguide (SIW) ?lter with multiple transmission zeros and good out-of-band rejection performance is presented in this paper. For this purpose, an orthogonal input/output (I/O) feeding structure directly connected to the substrate integrated waveguide (SIW) cavity is designed to split the resonant frequencies of the degenerate pair of mode. The ?lter can be modeled with a multi-path circuit formed by three modes (TE101, TE201 and TE102 modes) and weak cross coupling between I/O ports, thereby producing three transmission zeros which make the dual-band high selectivity. The o?set of the input/output ports shifts the second transmission zero to a lower frequency from the upper passband. Several ?lter prototypes are designed and fabricated for demonstration, and the measured results validate the new structure for high selectivity applications.
