Numerical Method of EM FieldsTelecom Technologies has extensive experience in numerical modeling of fields applicable to RF and microwave circuits. Accurate modeling is the key to success in high frequency integrated circuit design and frequency selective structures such as filters and diplexers. We can help you with your EM modeling challenges to ensure a successful design cycle. Examples of the areas include but are not exclusive to: » Microwave integrated circuit (MIC) and Monolithic Microwave Integrated Circuits (MMIC), passive components in microstrip lines and coplanar waveguides and RFIC. » Dielectric resonator structures including filters and antennas. » Metal resonator filters based on slotted ring resonators, cavity resonators, combline resonators. » Electromagnetic simulations using commercial and in-house software Numerical modeling, examples of of high frequency structures The figures shown below represent the results achieved by numerical modeling of cubical triple mode dielectric resonator filter. (i) EM simulation results. (ii) Evaluation coupling by measurement. (iii) Filter response measured and simulated.
Below are examples of simulated and measured results for a wide band very thin three-layer microstrip patch antenna. (a) Measured and computed return-loss (b) The experimental antenna structure.
