Abstract :
Using the method of moments, we analyze two types of microstrip-line antennas. They are connected and penetrated loop-line antennas, each consisting of loops and straight lines. It is found that circularly polarized radiation is obtained when the straight lines are appropriately shifted with respect to the loop centers.
