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.
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.
The stacked structure of an aperture-coupled cylindrical ( ) dielectric resonator DR antenna is studied experimentally. The effects of the offset and the air gap between the dri¨en and parasitic DR elements are in¨estigated. It is found that the bandwidth of the stacked structure can increase from t
This paper examines the concept of using an array of holes in a substrate for antenna performance impro¨ement. The finite-difference ( ) time-domain FDTD numerical technique is used to demonstrate the utility of the concept. The results clearly show the substantial radiation performance impro¨ement
