DESIGN AND REALIZATION OF A FREQUENCY RECONFIGURABLE MULTIMODE ANTENNA FOR ISM, 5G-SUB-6-GHZ, AND S-BAND APPLICATIONS

This paper presents the design and realization of a compact size multimode frequency reconfigurable antenna.The antenna consists of a triangular-shaped monopole radiator, originally inspired from a rectangular monopole antenna.Slots were utilized to notch the desired frequency while the PIN diodes were utilized to achieve frequency reconfigurabilit

Herbivore-carnivore interactions are fundamental to grassland ecosystem functionality and to the human cultures that have long depended on these ecosystems for their nutrition.However, a large literature has developed during the past century indicating that animal agriculture is responsible for numerous negative environmental impacts.In this paper,
