The design of simulated antenna is shown in Fig. 3.1. As can be seen from the figure‚ the Yagi-Uda antenna was built on a FR4 substrate (εr = 4.4) with the thickness of 1.6 mm. The design consists of one director element‚ a driven element and a ground plane acting as a reflector. To enhance the gain of the antenna coupling microstrips and metal plate were placed‚ that focus the entire beam towards a driven dipole.

POLYMERS 1. What are the two types of plastic? Thermoplastics and Thermosetting plastics 2. What is the difference between the molecular structures of the two plastics? The thermoplastics have long chains of molecules that are tangled together and have no fixed pattern but the thermosetting plastics have a long chain of molecule that are cross linked 3. What happens to the feel and properties of a plastic once a plasticiser is added during the manufacture of plastics?
