A Stacked Circularly Polarized Filtering Antenna With Crossed Slot

IEEE Antennas and Wireless Propagation Letters, 2023
This letter presents a stacked patch antenna for circularly polarized (CP) filtering without any additional filtering structures. The lower patches consist of a square patch with truncated corners, two sets of parasitic patches, and a 50 Ω microstrip ...

Square disks‐based crossed architectures of SnO2 for ethanol gas sensing applications—An experimental and theoretical investigation

, 2020
A facile synthesis and characterization of square disks‐based crossed architectures of SnO2 are reported in this paper. The prepared crossed architectures of SnO2 were analyzed by different techniques to study their structural, morphological, crystalline,

Freeness Conditions for Crossed Squares and Squared Complexes Dedicated to Professor Daniel Quillen

, 1999
Following Ellis, [9], we investigate the notion of totally free crossed square and related squared complexes. It is shown how to interpret the information in a free simplicial group given with a choice of CW-basis, interms of the data for a totally free ...
