A NOVEL 2D METAMATERIAL CRLH ZOR ANTENNA WITH A CIRCULAR MICROSTRIP PATCH CAPACITIVELY COUPLED TO A CIRCULAR RING MUSHROOM AND A NOVEL 2D METAMATERIAL CRLH ZOR ANTENNA WITH A RECTANGULAR MICROSTRIP PATCH CAPACITINELY COUPLED TO A RECTANGULAR RING MUSHROOM

摘要

PURPOSE: A CRLH 0-th resonant antenna of a 2D meta material structure of a circular microstrip patch structure capacitively coupled with a circular mushroom ring and a CRLH 0-th resonant antenna of a 2D meta material structure of a rectangular microstrip patch structure capacitively coupled with a rectangular mushroom ring are provided to reduce the size of an antenna by using a resonant property which shows a negative dimension. CONSTITUTION: A capacitively coupled circuit ring and a capacitively coupled rectangular mushroom ring include a short pin. The short pin is connected to a ground to give a left-handed propagation feature to the outside of a resonant patch antenna. The circular mushroom ring and the rectangular mushroom ring structure induce 0-th and -1-th resonance.
