The microstrip calculator determines the width and length of a microstrip line for a given characteristic impedance (Zo) and electrical length or vice versa. The substrate parameters (ε r and h) and the frequency of interest are required. EM: TALK - MICROSTRIP PATCH ANTENNA CALCULATOR The microstrip patch antenna calculator determines the length (L) and width (W) of a rectangular microstrip patch antenna for a given resonant frequency or vice versa. The substrate parameters (ε r and h) are required. If the ratio (L/W) is close to unity, the radiation pattern will be symmetric but may not provide a resonable inputimpedance.
VSWR CALCULATOR
The voltage standing wave ratio (VSWR) calculator determines reflection coefficient (GAMMA), VSWR, and return loss (dB) for a mismatched line. In addition, if GAMMA, VSWR, or dB is known, the calculator can convert between the three. If you only need to convert between GAMMA, VSWR, and dB, you can ignore Zo and ZL.

First the model of the microstrip patch antenna has to be drawn in HFSS. It consists of rectangular substrate and the metal trace layer as shown in Fig. 1. Note that a quarter-wave length transformer was used to match the patch to a 50 Ohm feed line. The dimensions of antenna can be found in the HFSS simulation file. EM: TALK - HFSS TUTORIAL 4: LEFT-HANDED MATERIALS Effective Medium Setup. In this section, the RHM and LHM's permittivity and permeability is setup in HFSS. The RHM will have a positive refractive index (PRI) of n=3.16, while the LHM will have a negative refractive index (NRI) of n=-3.16, where n=sqrt(μ·ε).To setup the permittivity and permeability required to realize each region, a RHM and a LHM needs to be created. EM: TALK - HFSS WAVEPORT CALCULATOR HFSS Waveport Size Calculator. Units do not matter; use same units for (w) and (h), waveport size will be in the same units as (w) and (h). The results should only be used as an estimate for the waveport size. Always perform a Solve Ports Only solution to ensure the waveport is correct. Calculation assumes that you are using a 50 Ohm microstrip NOISE FIGURE CALCULATOR where nf N and g N is the linear noise figure and linear gain, respectively of stage N. Noise figure is noise factor expressed in decibels (dB). The noise factor equation shows that stage 1 has the most influence in the overal noise factor/figure of a system. As a result, to reduce the total noise figure the first stage device should have low-noise and relatively high gain.

The Brillouin zone is the most fundamental region for defining the propagation vector for a unit-cell; basically if one can define all the propagation vectors in the Brillouin zone, one obtains the entire characteristic of the EM: TALK - ELECTROMAGNETICS AND MICROWAVE ENGINEERING FORUMS User Levels and Groups: What are Administrators?
