Abstract
AbstractA wideband electromagnetic‐compatible (EMC) chip antenna for application in the sliding mobile phone for WLAN/WiMAX dual‐network operation is presented. The proposed EMC antenna is easily fabricated by mounting a metal pattern onto a foam base of 30 × 6 × 6 mm3. The metal pattern comprises a radiating portion and a vertical ground plane. The radiating portion further consists of a shorted driven strip and a shorted parasitic strip, both of them together generating a wide bandwidth for 2.4‐GHz WLAN operation (2400–2484 MHz) and 2.5‐GHz WiMAX operation (2500–2690 MHz). The vertical ground plane functions as an effective shielding wall and allows the antenna to be in direct contact with nearby electronic components or conducting elements. Small variations on the performances of the proposed antenna for the sliding mobile phone in the slid‐open (talk) and standby conditions are also obtained. © 2006 Wiley Periodicals, Inc.
