Gr 4-6 - Ross offers 29 handmade gifts for children to create for their families and friends. Most of the materials can be found in the home and often involve recycling items (old felt-tip pen caps, film canisters, laundry-bottle caps, Christmas catalogs). For example, discarded children's socks can be used to make a "Jingle Bell Bracelet" and a cap for a "Snowman Antenna Ball" (useful for locating the car in crowded mall parking lots). The lists of materials are clearly illustrated as are the step-by-step instructions.
An accessible and practical tool for effective antenna design Due to the rapid development of wireless communications, the modeling of radiation and scattering is becoming more important in the design of antennas. Consequently, it is increasingly important for antenna designers and students of antenna design to have a comprehensive simulation tool.
The “bible of antenna engineering” fully updated to provide state-of-the-art coverage in antenna design and applications Edited by John L. Volakis, one of the world's leading authorities in antenna engineering, this trusted resource covers all the classic antenna types plus many new types and designs used in communications systems, satellites, radars, and emerging applications from WLAN to automotive systems to biomedical to smart antennas.
