Abstract
In this article, dual band circular polarization antenna is proposed, using coupled lines. A coaxial fed microstrip patch antenna generates the TM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</inf> mode and the required TM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">01</inf> mode to achieve circular polarization which is generated by coupled lines. The location of coupled lines with respect to the feed decides the sense of circular polarization. The reflection coefficient, axial ratio, gain, efficiency and radiation pattern characteristics of the antenna are investigated. An impedance bandwidth of 17.86% is achieved. Axial ratio bandwidth of 0.4% for Left Hand Circular Polarization (LHCP), and 0.8% for Right Hand Circular Polarization (RHCP) is achieved. The compact size of proposed antenna is very promising for current wireless communication systems.
