his paper investigates the design, parasitic patch measurement and characteristics of a probe-fed dual patch equilatsubstrate thickness h = 1.59 mm eral triangular antenna. A lossless foam material is sandwiched between the two patches to provide a mechanically stable and uniform height. It is shown that the foam thickness S separation height between the two patches plays a significant role in improving the impedance bandwidth of driven patch the antenna. A bandwidth of 13.2 persubstrate thickness h = 1.59 mm cent
