Broadband Microstrip Antennas
Girish Kumar,Kamla Prasan Ray +1 more
TL;DR: In this article, the authors provide an exhaustive coverage of broadband techniques, including the most up-to-date information to help users choose and design the optimum broadband microstrip antenna configurations without sacrificing other antenna parameters.
Journal ArticleDOI
Wide-band planar monopole antennas
TL;DR: In this article, a simple formula is proposed to predict the frequency corresponding to the lower edge of the bandwidth for each of these configurations, including square, rectangular, and hexagonal disc monopole antennas.
Journal ArticleDOI
Zinc Oxide Nanostructures for NO2 Gas–Sensor Applications: A Review
TL;DR: Various factors such as NO2 concentrations, annealing temperature, ZnO morphologies and particle sizes, relative humidity, operating temperatures which are affecting the NO2 gas sensing properties are discussed in this review.
Journal ArticleDOI
Antimicrobial properties of ZnO nanomaterials: A review
TL;DR: The recent developments for the fabrication of ZnO nanomaterials with variable morphologies, factors influencing the growth, morphology and surface defects, and various laboratory methods to evaluate the antibacterial activities toward Gram-positive as well as Gram-negative bacterial strains are reviewed.
