CONCLUSION
A PMMAαGIαPOF 2.5 Gbitrs transmission system with a record distance of 200 m has been reached, doubling the distance previously reported. The performances are mostly attributed to the spectral purity of the laser source, the use of a silicon APD receiver, and improved light-coupling arrangements that minimize back reflections from the fiber input end face into the laser source. We believe that the record result reported here is an important milestone that may encourage the development of polymer fiber systems using visible light.

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

Figure 8 Measured gain at 1.55 GHz for both antennas described in Figures 1 and3 The radiation patterns measured for both antennas with a rotating dipole at the central frequency of 1.5.5 GHz is shown in Figure 7. They present an axial ratio of 1.5 dB in the half-power beamwidth and are still better
