The development of e-textiles is fostering research in wireless energy transmission. This paper presents a purely textile 2.4 GHz WiFi band 2 × 2 rectenna array for RF energy harvesting. It utilizes the electromagnetically coupled microstrip patch antenna topology and a simple and precise construction method that provides a good performance repeatability to create multilayer microstrip textile patch antennas. The rectifier is implemented with Schottky diodes and it takes the voltage doubling configuration. An average DC power of 1,1 mW was measured for 14 μW/cm2 of RF input power density, while the end-to-end average power conversion efficiency (PCE) measured was 31%. The characterization of the end-to-end PCE was evaluated considering the physical size of the prototype to make the comparison with other designs easier. Measurements in a real WiFi scenario were also performed, demonstrating its feasibility for feeding e-textiles.

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.

While the revolution in antenna engineering leads to the fast-growing communication systems, Microstrip Patch Antennas (MPA) have proven to be the most unconventional discovery in the epoch of miniaturization. This paper incorporates the designing, simulation, and analysis of rectangular & circular microstrip patch antennas. The resonating frequency of the proposed patch antennas is 9 GHz, lying in the X band region and are designed on Rogers RT/duroid 5880 material having dielectric constant 2.2, using Ansys HFSS software. The proposed MPAs were compared on the basis of five performance parameters (Return loss, Bandwidth, VSWR, Gain and HPBW). It was observed that rectangular MPA has a higher value of return loss, VSWR and HPBW than circular MPA. Whereas, circular MPA has greater bandwidth and gain than rectangular MPA. The proposed antennas can be used in radar, wireless and satellite applications.
