Abstract
Research was done to learn the effects of dielectric materials in microwave signal transmission. The dielectric materials involved are Styrofoam, glass, wood, plastic and wet cloth foam, each material sized 10x10cm and width 5cm. Each material is put between transmitting antenna and receiving antenna in order to get the radiation pattern. The antennas used are Yagi-Uda antenna and dipole antenna, where Yagi-Uda antenna is functioning as transmitter while dipole antenna is the receiver. Frequency used in this research is I GHz. Wavelength for dipole antenna is set for 1h 1. Parameters investigated are radiation pattern, wave pattern and absorption loss. These parameters were used to make comparisons between antenna reception for different dielectrics materials and absorption loss toward antenna reception. Among the dielectric materials used in this research, absorption loss of wet foam (27.86% for E-plane and 8.l25% for H-plane) mostly affected the radiation pattern followed by Styrofoam (19.29% for E-plane and 1.875% for H-plane), plastic (14.64% for E-plane and 1.875% for H-plane), glass (13.21 % for E-plane and 11.25 for H-plane) and wood (11.79% for E-plane and 11.25% for H-plane).
