Abstract :
A new reconfigurable CRLΠ-TL was cascaded with a conventional RΠ microstrip TL to form a reconfigurable 0.18λ9 long zero-phase TL. The positive phase of the reconfigurable CRLΠ-TL was used to cancel the negative phase of the RΠ microstrip TL at two different frequencies. The reconfigurable RΠ/CRLΠ-0-ψ-TL presented in this work can be designed to have two different 0-ψ frequencies away from the stop band while simultaneously having good matching.
