A probe-fed microstrip patch antenna in a ¨ery high permitti¨ity substrate᎐superstrate configuration has been experimentally in¨estigated at 1.8 GHz. The microstrip patch is much smaller and has about the same gain as a con¨entional microstrip patch.

## CONCLUSION A PMMA᎐GI᎐POF 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
Experimental and simulation results of a coaxially fed U-slot microstrip antenna stacked with a rectangular patch are presented. Results include impedance bandwidth, copolar and cross-polar radiation patterns, and gain.
We present results of a recent investigation into a wide-band and high gain ( ) patch microstrip antenna using the finite-difference time-domain FDTD method. The substrate-superstrate resonance technique was used to increase the antenna element gain. An aperture-coupled rectangular patch microstrip
