应用于无线局域网的低剖面宽带双频微带天线的设计
Design of a wideband dual-frequency microstrip antenna with low profile for WLAN applications
摘要
Abstract
A single-feed, dual-frequency and wideband microstrip antenna with low profile is pro-posed for wireless local area network ( WLAN) applications. The radiation patch of the proposed anten-na is composed of two metal patches linked by three rectangular bridges. A shorted probe is inserted between the outer U-shaped patch and the ground, and the working bandwidth is broadened by the combination of the linked bridges and the shorted probe. The substrate of the proposed antenna with profile of 0.042λ consists of two FR4 substrates and an air layer in the middle, where λ is the free-space wavelength at 2.45 GHz. The measured results show that the operating bandwidths with S11 >10 dB are 2.39-2.50 GHz and 5.02-5.87 GHz, respectively. A desirable directional radiation pattern with the antenna gain of near 6.14 dBi at 2.45 GHz and 8.82 dBi at 5.5 GHz is obtained. The proposed antenna which can cover the whole IEEE 802.11a/b/n/ac operating bandwidths features a low-profile and high gain and has a good applied potential in engineering.关键词
