The use of organic semiconductor thin film of Alq3 to design parasitic capacitance coupling parasitic for a referenced circularly polarized microstrip patch antenna is demonstrated in this report. Results of the measurements lead to the conclusion that the Alq3 thin film capacitive coupling parasitic influences the circularly polarization significantly with little shift of operation frequency.
