Assessment of Composite Radome Impacts on the Signal Transmission of the 2.4 GHz Frequency Band

Optimal performance from the radome at 2.4 GHz can be achieved by choosing the right material. The avionics system is mounted on a radome made of Quartz, Glass, Aramid composite using an Epoxy Araldite LY 5052 matrix and made using the vacuum bag manufacturing method. To determine the effect of the type of material that the signal can penetrate properly, a dielectric constant test of various types of composite materials was carried out at a frequency of 50 Hz using the ASTM D150 standard. Verification of the signal penetration strength was carried out for the composite radome by means of a transmission test using a signal generator at 2 power levels of 0 and 10 dBm and a directional antenna in the anechoic chamber. The test results show that the quartz fiber composite has the lowest dielectric constant value and has the best signal penetrating ability. This shows that the value of the dielectric constant affects the signal permeability of the material.
