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.
