Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 463)

Abstract

UWB (Ultra-wideband) communication system is a short distance communication mode with low power and high speed. In order to improve the performance of UWB Antenna and increase the number of the FSS units in the Finite plane space, an UWB MEFSS unit structure is proposed. The size of the proposed unit is compact, which is 2 mm × 2 mm. And it has the characteristic of band-stop filtering in the UWB frequency scope. The proposed structure has stable filtering property for the electromagnetic wave which had different incident angle. Two-dimensional array consists of 11 × 11 MEFSS units which proposed in the paper. The two-dimensional array was placed under the elliptical monopole UWB Antenna as the reflection plane of the antenna. The analysis of frequency domain performance of the antenna shows that the antenna with MEFSS structure all had good impedance matching in the UWB frequency scope compares to the elliptical monopole UWB antenna, and the gain is increased 7.08 dB at most, which show that the proposed MEFSS structure can increase the gain of elliptical monopole UWB antenna effectively, and improve the radiation performance of antenna.
