MULTIBAND MONOPOLE U-SLOT PATCH ANTENNA WITH TRUNCATED GROUND PLANE

摘要

In this article, a wideband microstrip-fed monopole antenna with truncated ground plane is designed for multiband communication. The proposed antenna consists of a rectangular patch with two U-shaped slots, and a ground plane with two rectangular slots. By cutting two U-shaped slots in the radiating patch number of resonance is increased and more impedance bandwidth is achieved by cutting slots in ground plane which also improve impedance matching. The antenna is designed on the substrate FR4_epoxy to operate over four bands from 1.10-1.46 GHz, 2.23-2.91 GHz, 3.41-3.95 GHz, and 5.24-5.96 GHz with resonance frequencies of 1.21, 2.57, 3.61, and 5.60 GHz with % impedance bandwidth of 28.04, 26.45, 14.67, and 12.85% (for S-11 < -10 dB). The antenna is simulated using software HFSS v13. Simulated and measured results are presented to validate the effectiveness of the proposed antenna for 1.2 GHz GPS, 2.4/5.5 GHz WLAN, and 3.5 WiMAX applications. (C) 2016 Wiley Periodicals, Inc.
