Abstract:
1. A method for establishing a plurality of transmission lines (TL's) for a phased array antenna having a design frequency f 0 and a design frequency band, said TL's each having an overall phase and an overall phase slope over said frequency band, said method comprising the steps of: A) defining a Composite Right/Left Hand (CRLH) unit cell, said CRLH unit cell having a CRLH architecture; B) constructing a family of said CRLH unit cells using said CRLH architecture, said CRLH unit cells each having a physical length, a cell phase and a cell phase slope, said constructing step being accomplished so that said CRLH unit cells have substantially the same said physical length, but different said cell phases and different said cell phase slopes; and, C) for each said TL of said plurality, combining at least one of said family from said step B) with at least one Right Hand (RH) unit cell, so that each said TL in said plurality has substantially the same said overall phase and substantially the same said overall phase slope over said frequency band.
