✦ Synopsis

ranging from 5.53 to 5.98 GHz. Also, agreement between the calculation and measurement clearly seems good.

The far-field radiation patterns at 5.79 GHz for the proposed antenna was also measured and shown in Figure 4. Monopolelike radiation patterns in the E-planes ( x-z and y-z planes) and almost omnidirectional pattern in the H-plane ( x-y plane) are observed. In addition, the radiation characteristic of this design has been found to be stable, since similar patterns have also been measured at other operating frequencies across the band. The peak antenna gain for frequencies across the operating band has also been measured. The antenna provides a very stable peak gain within the range of about 5.2-5.7 dBi.

4. Conclusions

A CPW-fed folded-strip monopole antenna with a compact size has been proposed, and a constructed prototype suitable for RFID and even WLAN applications in the 5.8-GHz band has been demonstrated. The proposed antenna can be designed to have bandwidth of 450 MHz, monopolelike radiation performance, and peak antenna gain of more than 5.5 dBi in average, but has only 14 ϫ 8 mm 2 in antenna size. The antenna is mechanically robust and easy to fabricate and integrate with application-specific circuits.
