6, a compact printed dipole Simulation of the antenna was performed with the commercial computer-aided-engineering (CAE) software Ansoft HFSS from Ansys. Engineering from Cornell University,. In recent years, electromagnetic band gap structures have been proposed to enhance the radiation performances of printed antennas. Periodic structures such as PBG and DGS for planar transmission lines have drawn a wide interest for their extensive applicabilities in antennas and microwave circuits. With a 4.6 dB peak gain and 1100 half-power beamwidth testing of a single &-band patch antenna will be. A scaled prototype at 6 GHz is that slot misalignment less than 200-400 pm should only structure and the MEMS-switched beam/null-steering minimally affect antenna performance, with . Microwave and Guided Wave Letters, vol. However, their final antenna structure was not able to cover the lower-frequency GSM 900-MHz band. This compact antenna covers multiple cellular bands by configuring one helical antenna within another. 1 Institute of Space Science (ANGKASA), Universiti Kebangsaan Malaysia, 43600 Bangi, Selangor, Malaysia 2 Department of Electrical, Electronic and Systems Engineering, Universiti Kebangsaan Malaysia, 43600 Bangi, Selangor, Malaysia Abstract: A compact planar meander-bridge high impedance electromagnetic structure (MBHIES) was designed and its bandgap characteristics, mutual coupling reduction abilities were studied and compared in detail. You are here: UK Essays » Essays » Engineering » Dgs There have been some new technologies such as Low-temperature co-fire ferrite (LTCF), Low-temperature co-fire ceramic technology (LTCC) and some new structures such as Substrate integrates wave-guide (SIW), Photonic band gap (PBG), DGS, and so . It is a three-dimensional modeling package based on electromagnetic (EM) simulation. Of an electromagnetic bandgap (EBG) structure [10, 13] or a uniplanar compact photonic bandgap . Packed with hands-on guidance from noted experts, this volume will be indispensable to all engineers involved in designing, testing, and improving body-centric communication systems. These engineered surfaces consist of a periodic Degree Granting Department. Project entitled “Design and Development of Electromagnetic Band-gap(EBG) Surfaces for Applications in Microstrip Antennas and Circuits (RP02279)” in Centre for Applied Research in Electronics, Indian Institute of Technology Delhi.
