Thermal Effects in Microstrip Line CouplersAuthor(s): Nirmal Kumar
The microstrip structure suffers from conductor and dielectric losses due to flow of electromagnetic power through it. These losses generating heat in the strip conductor and the supporting dielectric substrate are called thermal effects in the structure. For the coupled microstripline coupler, the thermal effects produced are the functions of the strip width, substrate height, permittivity, spacing between two strip conductors and operating frequency. The rise of temperature in the structure is utilized in preserving foods, seeds, other agriculture products and in warming the surroundings.
