Abstract :
A tri-polarization antenna with providing three orthogonal polarizations is designed and analyzed. Two slot coupling fed microstrip antennas and a monopole with circular disk loading are integrated in one structure. The operating bandwidth of the proposed antenna is 370MHz. By introducing a capacitive coupling strip, the isolations between each two feeding ports are better than -15 dB.
