A Compact Triangular Slot Array Multiband Antenna for Wireless Applications

Xiao-ying RAN, Zhen YU


A novel compact triangular slot array multi-broadband planar antenna is proposed for mobile handsets in the paper. The antenna has an inverted triangle structure radiator with fourteen units triangular slot array and coplanar waveguide (CPW) feed structure. The antenna can cover more than ten mobile applications in three broad-bands with -10dB bandwidth of 69.57% (0.613-1.267GH) for UHF (606-806MHz), GSM900 (880-960MHz), LTE44 (703-803MHz), CDMA2000 (825-880,885-960MHz), 30.17% (1.97-2.67GHz) for DCS1800 (1710-1880MHz),TD-SCDMA (1880-2025MHz,2300-2400MHz), WCDMA (1920-2170MHz,1755-1880MHz), LTE33-41 (1900-2690MHz), Bluetooth, GPS, COMPASS, GLONSS, GALILEO, WLAN (802.11b/g/n:2.4-2.48GHz), and 31.17%(4.17-5.71GHz) for WLAN (802.11a/n:5.15-5.35GHz) wireless applications. The antenna is fabricated on a 1.6 mm-thick FR4 substrate with dielectric constant of 4.4, and the size is 60*55mm2. The good agreement between the measurement results and the simulation validates the proposed design approach and meets the requirements for various wireless applications.
