Abstract :
In this paper, a wideband compact circularly-polarized (CP) patch antenna is proposed. This patch antenna is excited by a meandering probe which is implemented in multi-layered substrates. The proposed antenna is wide in both impedance and axial ratio (AR) bandwidths, which respectively are 49% (for reflection coefficient<;-10dB) and 8.64% (for AR<;3dB). The peak gain within the AR bandwidth is 7.3dBic and the gain variation is less than 0.5dB.
