A microstrip-coupled CDRA excited in the HE mode 11⦠is theoretically and experimentally in¨estigated. The antenna is simulated using the finite-element method. The parameters considered are the resonant frequency, return loss, radiation pattern, directi¨ity, unloaded Q-factor, and impedance bandwid

β¦ Synopsis
Figure 6 Discrepancy between measured and actual disturbance positions
obtained with the sensor is approximately 5 m for 200 m of sensing fiber. We believe that the measurement accuracy can be improved by developing a better signal processing technique and by using polarization-maintaining fiber.

A hemispherical dielectric resonator antenna excited by a microstrip feedline through a narrow slot in a thick ground plane is studied theoretically and experimentally. A numerical method based on a combination of the spectral Green's function, modal Green's function, and the method of moment is use
this graph is meaningful only for integral values of n. We have incorporated in Figure 5 the case n s 3, which we w x discussed in an earlier paper 12 . We find that the general tendency is that, as one increases the number of loops, the cutoff Β¨-value for a mode increases. We may thus say that, in
