In this paper, design and manufacturing of a composite right/left-handed carved planar (CRLH-CP) antenna with epsilon - mu constitutive parameters is introduced. The composite right/left-handed transmission line (CRLH-TL) is introduced as a general TL possessing both left-handed (LH) and righthanded (RH) natures. The proposed antenna is constructed of four CRLH unit cells, each of which occupies space of 0.004 lambda(0)x0.01 lambda(0)x0.001 lambda(0), where lambda(0) is free space wavelength at 0.5 GHz. The antenna practical bandwidth is 120%, so that the proposed antenna can be used for frequency band from 0.5 GHz to 2 GHz in measurement. Also, the antenna gains and radiation efficiencies at the operational frequencies f=0.7, 1.5 and 2 GHz are 3.8 dBi and 53%, 4.85 dBi and 68.5%, and 4.3 dBi and 60.2%, respectively. According to the results, the proposed minimized ultra wideband (UWB) antenna is a good candidate to use in the RF electronic devices and embedded systems.
