| Abstract | ||
| In this work, many techniques are suggested and analyses for rectangular microstrip antenna (RMSA) operating in X-band for 10 GHz center frequency. These approaches are: lowering quality factor, shifting feeding point , using reactive loading and modification of the patch shape. The design of a RMSA is made to several dielectric materials, and the selection is based upon which material gives a better antenna performance with reduced surface wave loss. Duroid 5880 and Quartz are the best materials for proposed design to achieve a broader Bandwidth (BW) and better mechanical characteristics than using air. The overall antenna BW for RMSA is increased by 11.6 % with Duroid 5880 with shifted feeding point and with central shorting pin (Reactive loading) while that for Quartz is 17.4 %. Modification of patch shape with similar improving techniques gives an overall increasing VSWR bandwidth of 26.2 % for Duroid 5880 and a bandwidth of 30.9 % for Quartz. These results are simulated using Microwave Office package version 3.22, 2000. | ||
