Abstract
In this paper, a novel low profile dual feeding microstrip antennas with microstrip and H-shaped aperture feeding are proposed to achieve high isolation and easy feeding, and the validity of the proposed antennas is demonstrated experimentally. In the proposed single and 1$\times$4 array antenna, the measured isolations are less than -49 dB and -48 dB, impedance bandwidths are 4 % at 12.5 GHz and 2.1 % at 14.25 GHz for the VSWR<1.5 in both antennas and maximum gains are 8.25 dBi and 14.2 dBi.
