Abstract

              This paper presents a microwave frequency band functioning monopole antenna with frequency reconfigurability. On an FR-4 substrate with a relative permittivity of 4.4 and a height of 1.6 mm antenna can be printed. An antenna can operate in various modes by placing two RF (PIN diode) switches between radiating patches. The antenna working in three modes that covers six different bands, with two dual bands of 3.8 GHz / 7.5 GHz, 3 GHz / 7.1 GHz in Modes 1 & 2 respectively, and 2.8 GHz / 6.7 GHz in Mode 3. The antenna has good Voltage Standing Wave Ratio (VSWR) for all working bands. The gain at comparable resonant frequencies ranges from 1.74 to 4.75 dBi. At each frequency, the achievable bandwidths range from 8.8 to 46.6 %. The structure is designed in High Frequency Structure Simulator (HFSS).  The antenna can be used in WiMAX, WLAN, C-Band, 5G, and Sub-6Hz wireless communications.
