Microstrip line

Transmission lines are means of transporting RF energy between subsystems . They have many applications between exciter OUT port to the transmitter IN port and also from transmitter OUT port to the antenna INPUT port.

Often, microwave engineers deal with a term named “effective travel distance ”, which is the distance along the transmission line, at which the wave amplitude becomes 1/e times the starting amplitude (at x = 0). Clearly, at this point, αx = 1. The effective dB gain is 20log10 e−1 = 8.68dB.

Types of transmission line include parallel line (ladder line, twisted pair), coaxial cable, and planar transmission lines such as stripline and microstrip . The higher the frequency of electromagnetic waves moving through a given cable or medium, the shorter the wavelength of the waves.
