Abstract
This article presents a miniaturized patch antenna for wireless applications at 2.4 GHz. A conventional microstrip‐fed patch antenna is firstly designed to operate close to 10 GHz. Then, the antenna is modified to operate at lower frequency without changing the antenna dimensions. First, the ground plane is replaced with a uniplanar‐compact‐photonic‐band‐gap (UC‐PBG) structure. Then, a backed conductor is placed close to the UC‐PBG and connected to it through four vias. These two modifications are utilized to decrease the lower operating frequency of the antenna from 9.7 to 2.42 GHz. Thus, a 75% size reduction factor is obtained. © 2008 Wiley Periodicals, Inc.
