Abstract:
1. A pattern and/or polarization reconfigurable antenna comprising: at least one Composite Right Left Handed (CRLH) unit cell including a standard transmission line with added series capacitance and shunt inductance and adapted to radiate an electrical field; and at least a variable capacitance and/or inductance in series with the shunt inductance and at least a variable capacitance and/or inductance in parallel with the series capacitance, whereby said at least a variable capacitance and/or inductance in series with the shunt inductance and said at least a variable capacitance and/or inductance in parallel with the series capacitance are responsive to at least two DC biases used to independently control the variable capacitance and/or inductance in parallel with the series capacitance and the variable capacitance and/or inductance in series with the shunt inductance to thereby control the group delay of the transmission line and/or a polarization of the radiated electrical field.
