【 摘 要 】

References(7)This study designs a film monopole antenna for WiBro (wireless broadband internet, 2.3-2.4GHz) and WLAN (wireless local area network, 2.4-2.48GHz) bands. A variety of design parameters were used to optimize frequency properties, and radiating and grounding elements were placed on the same plane for maximized radiation efficiency. Cloverleaf-shaped radiating elements were used to induce a phase difference of 180 degrees and thus obtain improved bandwidth. This paper presents the possibility of realizing broadband by using parasitic elements. The antenna created in this study achieves a peak gain of up to 3.18dBi and satisfies WiBro (2.3-2.4GHz) and WLAN (2.4-2.48GHz) bands with a bandwidth of 2.30-2.54GHz (9.8%) at -10dB or lower.
