摘要：
A compact coplanar waveguide fed multiband antenna is proposed and investigated. The proposed antenna consists of a rectangular radiating patch and dual meander strips with a defected ground plane. The size of the fabricated prototype is 28.3 × 24 × 1.59 mm3. The proposed antenna radiates at three different resonant modes, which cover 2.29–2.63 GHz, 3.26–3.96 GHz, and 4.97– 6.10 GHz. The proposed antenna can be used for TD-LTE 2300/2500 (2.305–2.4 GHz), WLAN (2.4– 2.4835 GHz and 5.15–5.875 GHz) and WiMAX (2.3–2.4 GHz and 3.3–3.7 GHz) applications. The proposed antenna exhibits an omnidirectional radiation pattern in the H-plane and a dipole-like radiation pattern in the E-plane. The measured peak gains are 2.64/4.48/6.08 dBi at 2.4/3.5/5.5 GHz operating frequency bands, respectively. © 2017, Electromagnetics Academy. All rights reserved.
