Design of Compact Penta-Band and Hexa-Band Microstrip Antennas

AbstractThis paper presents the design of two multi-band microstrip antennas. The antenna-1 gives Penta-Band and antenna-2 gives Hexa-band in the WLAN band. The frequency bands of the antenna-1 are Bluetooth 2.47 GHz (2.43 GHz–2.54 GHz), WiMax band 3.73 GHz (3.71 GHz–3.77 GHz), WLAN 5.1 GHz (4.99 GHz–5.13 GHz), upper WLAN 6.36 GHz (6.29 GHz–6.43 GHz), C band band 7.42 GHz (7.32 GHz–7.50 GHz) and the antenna-2 are WLAN band 2.6 GHz (2.56 GHz–2.63 GHz), 3.0 GHz (2.94 GHz–3.05 GHz), WiMax band 3.4 GHz (3.34 GHz–3.55 GHz), 4.85 GHz (4.81 GHz–4.92 GHz), WLAN 5.3 GHz (5.27 GHz–5.34 GHz) and upper WLAN 6.88 GHz. Both the antennas are fabricated and their measured results are presented to validate the simulated results. Proposed antennas have compact sizes and good radiation performances.
