Abstract
A new technique is developed to best locate the coaxial feed of a circularly polarized stacked microstrip antenna (CPSMA) with the objective of improving the axial-ratio (AR) bandwidth and CP quality of the antenna. In the proposed technique, we move the single feed on an arc between the diagonal and main axis of the driven patch to optimize CP performance. An antenna based on this technique has been designed, and a prototype has been fabricated and tested. The antenna measurements show an excellent 14.8% AR bandwidth, 7.7dBi gain (over the impedance bandwidth) and 19.5% impedance bandwidth.
