摘要
This article describes a compact planar microstrip antenna for multiband transceiver application. The proposed antenna consists of a combination of E-shaped and C-shaped radiators that are excited via a common microstrip feed-line. Embedded in the ground-plane are included an open- and short-ended slots whose purpose is to enhance the antenna's impedance match and increase the number of bands in which the antenna can operate. A prototype antenna was fabricated on a standard FR4 substrate with epsilon(r) of 4.4 and thickness of 1.6 mm, and its reflection-coefficient and radiation patterns were measured to demonstrate its feasibility. Measurements confirm the antenna can simultaneously operate over the frequency bands of: DCS (1.71-1.85 GHz), PCS (1.85-1.99 GHz), UMTS (1.92-2.17 GHz), Wibro (2.3-2.39 GHz), WLAN+ Bluetooth (2.4-2.48 MHz), WIMAX (2.5-2.69 GHz), WIMAX (3.3-3.5 GHz), HIPERLAN2 (5.15-5.35/5.47-5.725 GHz), and WLAN (5.15-5.35/5.725-5.825 GHz). The antenna has dimensions of 30 x 40 x 1.6 mm(3), which is compatible with the requirements imposed by portable wireless systems.
