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 ε 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 × 40 × 1.6 mm 3 , which is compatible with the requirements imposed by portable wireless systems. © 2015 Wiley Periodicals, Inc.
