It is located in Mesa, Arizona and has been helping the elderly since 1989. I picked Courtyard Towers to do my service project because my grandma is currently living there and I also enjoy working with the elderly. Courtyard Towers has 98 employees and 180 residents. On each floor there are 16 residents with 2 caregivers, a nurse, and an activities director. . By: James VE3BUX. Definition. The Modern Dictionary of Electronics defines an antenna as:. That portion, usually wires or rods, of a radio transmitter or receiver station used for radiating waves into or receiving them from space. It changes electrical currents into electromagnetic waves, and vice versa.. Lesson 2. Learning Outcomes. Be able to analyse and research a 3 dimensional problem in art and design.

What is an Antenna?. An electronic device that is used either for radiating electromagnetic energy into space or for collecting electromagnetic energy for space. Any wire carrying AC current will radiate electromagnetic waves and an electromagnetic wave will induce a voltage in a length of wire.
