Analysis and Design of a New Dual Band Microstrip Patch Antenna Based on Slot Matching Y-Shaped

A new compact microstrip slot antenna with Y-shaped coupling aperture is proposed. This antenna is based on a rectangular form with a microstrip fed line for excitation, and consists of slots on the edge of the radiation patch to provide dual-band operation. The design and simulation of the antenna were performed using CST Microwave Studio simulator. A prototype of the proposed antenna has been constructed and tested. In order to validate the return loss of the prototype antenna, the experimental results are presented. The results show two available bands with –10 dB band S at 2.7 GHz and band C at 5 GHz. Also, good radiation performance and antenna gain over the two frequency ranges have been obtained. Computation results confirm the experimental findings

Introduction to the special issue “Sustainability Issues of Food Processing and Packaging: the Role of Life Cycle Assessment”

The International Journal of Life Cycle Assessment is quite familiar with the topic of sustainability of food processing and packaging and, in fact, a remarkable number of LCAs and LCSAs have been published thus far in the journal. This special issue aims at furthering the understanding and deepening of such a topic with special regard to product and process innovation, through expanded capability and greater ranges of the scenarios and systems analysed. It was designed to motivate researchers to address issues of novelty and scientific relevance in the assessment and improvement of sustainability in the food processing and packaging sector
