主　　题：Monopole antennas 

摘      要：This research aimed to design a sea pimp-shaped monopole antenna by using etching and cutting techniques, combined with the addition of reflector, to modify the antenna structure to support the bandwidth standard according to GSM-850 (0.82–0.90 GHz), GSM900 (0.88–0.96 GHz), DCS (1.72–1.88 GHz), PCS (1.85–1.99 GHz), UMTS (1.92–2.17 GHz), 5G Band40 (2.30–2.40 GHz), LTE41 (2.496–2.690 GHz), and WLAN IEEE 802.11b/g/n (2.4–2.48 GHz). This antenna used a galvanized metal sheet with a conductivity of 3.56 × 107 s/m to fabricate the structure of the radiator, ground plane, and reflector. The reflector modifies radiation patterns and increases the gain of the antenna. The antenna structure used the CST program for simulation to determine the optimal parameters and property values. As a result of replication, the antenna had dual bands with a reflection coefficient (S11) at 915 MHz (736–1040 MHz) of −26.70 dB and a frequency at 2.28 GHz (1.68–2.94 GHz) of −20.15 dB. The antenna gains are 6.70 and 8.47 dBi, an increase of 83.56% and 44.04% over the antenna without a reflector, respectively. The antenna had a unidirectional pattern in all the frequency ranges which can be utilized for the purpose of RF energy-harvesting (RF-EH) systems to provide power to low-power electronic systems. © 2024, Electromagnetics Academy.
