A compact, triple-band (WiMAX, WLAN and X-Band uplink satellite communication) monopole antenna is reported in this paper. The geometry of the proposed antenna consists of a pentagon-shaped patch along with symmetrical hook-shaped resonators and one vertical slot. The reported antenna works at three unique frequencies centered at 3.5 GHz, 5.4 GHz, and 8 GHz, covering absolute bandwidth of 900 MHz (3.2-4.1 GHz), 800 MHz (5.1-5.9 GHz), and 1.6 GHz (7.3-8.9 GHz), respectively. This antenna possesses good gain and high efficiency at all operating bands. The presented antenna has simulated gain (efficiency) of 4 dBi (78%), 4.2 dBi (79.95%), and 4.2 dBi (85.8%) at 3.5, 5.4, and 8 GHz, respectively. The operating bands of the presented antenna can be tuned independently by varying certain correlated parameters. All the simulations are carried out using High Frequency Structure Simulator (HFSS 13.0). The hardware of the simulated antenna is successfully constructed and tested for validation of simulation results. A reasonable match between the simulated and measured results is observed at the operating bands.
