The new 3-D proposed structure has a stop band at 2.45 GHz. This stop band is the operating frequency for common microwave heating devices. The structure is periodic. The infrared emissions are passed through a large enough opening inside the microwave cavity in order to allow the temperature of the object inside to be read by the thermopile installed outside the chamber. Using the FE Eigen analysis...
As the majority of the radio localization applications are adopting the 5.8 GHz band, in this paper, an elliptical slotted patch antenna with a defected ground structure is proposed for wideband Applications. The −10dB S11 bandwidth is 7.8GHz (4.1 GHz to 11.9 GHz).. The effective directional radiation patterns and the large impedance bandwidth has been witnessed from simulation results. The proposed...
Eigenvalue analysis of a periodic structure by the finite-element method gives its Floquet propagation constant at a given frequency. Using this method directly to find the dispersion curve is computationally expensive, particularly in 3-D, because a large matrix eigenproblem must be solved at each frequency. The cost can be lowered by applying model-order reduction. A full-size eigenproblem at one...
