Multi frequency antennas are in high demand as the wireless communication system is developing rapidly. To access internet in a mobile device, 2G-5G and WLAN are used that covers 1.8 GHz – 6 GHz. This paper proposes a design of low profile multiband monopole antenna for all 2G-5G communications, WLAN and for WiMAX application. The antenna design has a diamond shaped radiator, a cylinder to achieve better resonance, and a defective ground. The proposed antenna has a compact size of 30 mm x 44.5 mm. This antenna covers 2G (1.8 GHz), 3G (2.1 GHz), 4G (2.4 GHz), 5G (3.5 GHz), WLAN (2.4/3.6/5 GHz) and WiMAX (2.3/3.5/5.8 GHz) and is shown from the measured results. From these results it is shown that the produced antenna produces six distinct bands with good the simulation outcomes.
