Beam scanning using microstrip line on biased ferrite [PDF]
The beam scanning properties of a 2-element patch array fed by a microstrip reed situated on a ferrite substrate are presented. Biasing the ferrite changes the phase length or the microstrip line, scanning the beam by up to 40 degrees. The resulting scan

An analysis of microstrip with rectangular and trapezoidal conductor cross sections [PDF]
The finite-difference time-domain (FDTD) technique is used to analyze boxed microstrip with both rectangular and trapezoidal cross sections. It is confirmed that the exact shape of the conductor has a marked effect on the effective permittivity of the ...

Fast finite difference time domain analysis of microstrip patch antennas [PDF]
Although the finite-difference-time-domain method has been successfully used to model microstrip-fed patch antennas, this has been achieved using uniform grids.

Scanned microstrip arrays using simple integrated ferrite phase shifters [PDF]
A phase-steered microstrip antenna array is presented, suitable for application as a mobile vehicle satellite terminal. Phase shifters are implemented on a hybrid dielectric-ferrite substrate, and use is made of the phase transition near the cut-off ...

Stable inclusion of a priori knowledge of field behaviour in the FDTD algorithm: application to the analysis of microstrip lines [PDF]
A general methodology for incorporating a priori knowledge into the FDTD algorithm has been presented. In this contribution the technique has yielded a modified FDTD algorithm for the analysis of a microstrip; this method has been shown to be both more ...
