Experiment 3: EXPERIMENTS WITH λ/2, λ, AND 3λ/2 DIPOLES

The three dipoles presented in this experiment are center-fed dipoles. Students are called to understand that the electromagnetic fields are a result of the RF current behavior on the wire. The experiment examines the notions of input impedance, resistive and reactive impedance, inductive and capacitive reactance and current in phase or out of phase with the objective to give students a clear understanding of these dipoles.

Experiment 4: HALF-WAVE FOLDED DIPOLE ANTENNAS

The folded dipole antenna consists of two parallel dipoles connected into a narrow loop. The experiments get the students familiar with the characteristics of the half-wave folded dipole antenna and with the use of baluns for impedance transformation.

Experiment 5: MONOPOLE ANTENNAS

The objective of this exercise is to familiarize students with the characteristics of both standard monopole antennas and drooping monopole antennas. Students are asked to plot the radiation patterns over a conducting ground plane and observe the behavior of a monopole used without a ground plane. They will compare the directive gain of both a λ/2 dipole and a λ/4 monopole.

Experiment 6: LOOP ANTENNAS

Loop antennas with a loop length of λ (full-wave loop antennas) are useful because they offer reasonable gain and convenient input impedance. The experiment familiarizes the students with the characteristics of small loop antennas.

Experiment 7: PARASITIC ARRAY (YAGI-UDA) ANTENNAS

The Yagi antennas are used in several applications. When the students complete this experiment they will be familiar with parasitic array antennas of the Yagi-Uda type. They will construct such antennas in different configurations and measure their characteristics.

Experiment 8: RECTANGULAR PATCH ANTENNA (MICROSTRIP TECHNOLOGY)

A microstrip antenna consists of a patch of conductive material separated from the ground plane by a thin layer of substrate dielectric material. The microstip is well suited for low profile and conformal antennas. The experiment aims to get students familiar with the patch antenna and with the microstip technology used to implement patch antennas.
