Abstract :
In this paper, a wideband monopole antenna with high gain characteristics has been proposed. Number of slits was introduced at the far radiating edge to transform it to multiple monopole radiators. Partial ground plane has been used to widen the bandwidth while by inserting suitable slits at the radiating edges return loss and bandwidth has been improved. The proposed antenna provides high gain up to 13.2dB and the achieved impedance bandwidth is wider than an earlier reported design. FR4 Epoxy with dielectric constant 4.4 and loss tangent 0.02 has been used as substrate material. Antenna has been simulated using HFSS (High Frequency Structure Simulator) as a 3D electromagnetic field simulator, based on finite element method. A good settlement has been found between simulated and measured results. The proposed design is suitable for GSM (890-960MHz), GPS (L1:1575.42MHz, L2:1227.60MHz, L3:1381.05MHz, L4:1379.913MHz, L5:1176.45MHz), DCS (1710-1880MHz), PCS (1850-1990MHz), UMTS(1920-2170MHz), Wi-Fi/WLAN/Hiper LAN/IEEE 802.11 2.4GHz (2412-2484MHz), 3.6GHz (3657.5-3690.0MHz) and 4.9/5.0GHz (4915-5825MHz), Bluetooth (2400-2484MHz), WiMAX 2.3GHz (2.3-2.5GHz), 2.5GHz (2500-2690 MHz), 3.3GHz, 3.5GHz (3400-3600MHz) and 5.8GHz (5.6-5.9GHz) & LTE applications.
