Uma Shankar Modani, Anubhav Kanwaria, Gajanand Jagrawal . Notched Triangular Patch Antenna for Polarization Reconfigurability. National Seminar on Recent Advances in Wireless Networks and Communications. NWNC, 2 (April 2014), 17-21.
This paper proposes a reconfigurable microstrip patch antenna with polarization states being switched between left-hand (LH) and right-hand (RH) circular polarizations (CP). The CP mode has been excited by perturbation element which is two parallel notches at the base of triangular patch. Two PIN diodes are placed on each notch to alter the current direction, which determines the polarization state. As notch rightwards (leftwards) to base center of triangular patch is shorted between the inside of the notch and the triangular patch, the proposed antenna yields left (right) handed circular polarization. This reconfigurable patch antenna with agile polarization has good performance and concise structure, which can be used for 5. 77 GHz wireless communication systems.
