Dual-band Bisected Psi Antenna for 3G, Wi-Fi, WLAN and Wi-MAX Applications

摘要

This paper presents an inexpensive and simple dual-band bisected psi antenna for 3G, Wi-Fi, WLAN, and WiMAX applications is presented. The antenna comprises a bisected psi-shaped patch on a low-price FR4 substrate with a cropped ground plane on the other side, and is fed by a 50Ω. microstrip line. It operates at two distinct frequency bands of 1.87-2.76 GHz and 5.16-5.75 GHz with |S_(11)| ≤ -10 dB.
