A novel compact reconfigurable multi-band antenna

A novel compact antenna with the ability of reconfigurable multi-band applications is proposed. This achieved by integrate the compact 38mm × 38mm antenna with three RF switches. The activation of particular RF switches arrangement would then determine the frequency flexibility. The presented antenna competents to execute up to five multi-bands. The operating frequencies are band 1 (2.72 - 11.8GHz), band 2 (2.4 - 4GHz, 5.3 - 11.6GHz), band 3 (2.7 - 6.5GHz, 7.1 - 11.6GHz), band 4 (2.7 - 4.4GHz, 5.2 - 6.5GHz, 7.1 - 11.7GHz) and band 5 (2.6 - 3.5GHz, 4.8 - 7.0GHz, 7.4GHz - 11.5GHz). The presented antenna generates a proficient divisive radiation pattern at frequencies of 3 GHz, 6 GHz and 9 GHz. The developed antenna has great potential for military and cognitive radio applications.
