Reconfigurable TX/RX Antenna Systems Loaded by Anisotropic Conductive Carbon-Fiber Composite Materials

We present the potential use of reinforced continuous carbon fiber composite (RCCFC) material to build reconfigurable transmitter/receiver communication systems. The frequency agile characteristic is obtained by the rotation of the antennas on the ground plane which is made of anisotropic RCCFC material. The current distribution on the RCCFC composite ground plane can be controlled by exciting the desirable modes and eliminating the unwanted ones. Probe-fed rectangular microstrip-patch antennas are fabricated and the reconfigurable characteristics are investigated both numerically and experimentally.
