A novel compact tree-design antenna (NCTA) with the ability of reconflgurable ultra-wideband (UWB) of 3.1GHz to 10.6GHz to flve multi-narrowband applications is proposed. This antenna has a novel radiating element design that consists of seven small circles (7- fllter) surrounding a central circle. Moreover, the NCTA incorporates the 7-fllter that functioned as fllter into the antenna design. The compact 38mm£38mm antenna integrates three PIN diode switches, which are connected to a single National Instrument Data Acquisition (NI-DAQ) Board. The DAQ itself is controlled (ON/OFF state) by a virtual instrument known as \Lab VIEW Interface Software". The activation of speciflc PIN diode switches in the conflguration that is controlled by the DAQ then, in turn, determines the frequency agility. The presented antenna is capable of performing up to flve multibands. The operating frequencies are as follows; 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). Furthermore, the antenna has a gain of up to 6dBi which is considered better than that of conventional antenna. The proposed antenna produces a proflcient divisive radiation pattern at 4 and 6GHz.
