Abstract

In this paper, a conventional microstrip-fed patch antenna that operates close to 10 GHz is modified to operate close to 2.5 GHz, without changing the dimensions of the antenna. First, the ground plane is replaced with a Uniplanar- Compact-Photonic-Band-Gab (UC-PBG) structure. Then, a backed conductor is placed close to the UC-PBG and connected to it through 4 vias. These two modifications are utilized to decrease the lower operating frequency of the antenna, which implicitly means decreasing the size of the antenna. Numerical study of the parameters of the UC-PBG structure is performed and presented to understand the effect of each parameter on the return loss of the antenna, and also to improve the size reduction factor. The small size of the proposed antenna makes it suitable for wireless communications applications.
