Antennas made simple: making antennas with recycled materials

The fabrication of antennas with recycled materials but with good performance is possible by using the classical formulation from textbooks. Several antenna designs built with materials found at home are shown, and their performance is measured with professional equipment to assess an acceptable agreement between simulations and measurements. Practical design and fabrication of antennas made with used materials and operating at WiFi bands will surely stimulate students of basic topics of antennas to fabricate and test their own designs.
