✦ Synopsis

use of the printed inverted-F monopole antenna with a parasitic shorted strip, the proposed AiSiP can provide a wide operating bandwidth of 470 MHz centered at about 2450 MHz, allowing it to easily cover the 2.4 GHz band for WLAN operation. Results also indicate that, when the proposed AiSiP is employed in the wireless device for practical applications, the relative position of the AiSiP to the system ground plane of the wireless device has strong effects on the antenna performances of the AiSiP. There are large frequency shifting and bandwidth variations observed for the integrated antenna of the AiSiP. The related effects become more significant when the AiSiP is employed in the wireless device with a larger system ground plane size. However, with the proposed AiSiP having a wide operating bandwidth, the possible frequency shifting and bandwidth variations owing to the relative position variations of the AiSiP to the wireless device ground plane are easily covered. In addition, good radiation characteristics over the operating bandwidth of the AiSiP have been observed. With these attractive antenna performances obtained, the proposed AiSiP is very promising for application in the wireless device to provide a complete communication function, without the external antennas required.
