A heterogeneous substrate multiband microstrip patch antenna with various shapes fed by a rectangular microstrip feed line is proposed in this paper with a total area of 73.3 x 127.85 x 3.2 mm3 . The antennas are printed on a heterogeneous substrate with the combinations of easily available materials like FR4_epoxy, Air and Taconic RF-30 with relative permittivity of 4.4, 1 and 3.The multiband characteristics are achieved by choosing a proper selection of positions and dimensions of slot in the substrate below the patch. The various structures of microstrip patch antennas like rectangular, square, circular, elliptical and triangular covers L (1-2 GHz), S (2-4 GHz), C (4-8 GHz) and X (8-12 GHz) bands and used for various applications like Low Density Radio Communications Link (LDRCL), Communication satellites, Wireless LAN-802.11b, 802.11g, Bluetooth and WiMAX applications. All the antennas are designed and imitated using Ansoft HFSS 13.0 antenna software. The prototype of various shapes of proposed antennas are fabricated and measured and results in good return Loss, VSWR, resonant frequency, radiation pattern and the antenna gain.
