A compact quad-band hybrid antenna for Com- pass/WiMAX/WLAN applications is proposed. The hybrid antenna is designed based on the method of combining a composite right/left- handed transmission line (CRLH-TL) unit cell with a meandered monopole and wide multi-band characteristics are achieved by merg- ing some of resonance frequencies of the CRLH-TL unit cell and me- andered monopole together. Coplanar waveguide (CPW) is used as a parallel excitation for both the CRLH-TL unit cell and meandered monopole. A prototype of the proposed hybrid antenna has been con- structed and experimentally studied. The measured results show that four distinct operating bandwidths with 10dB return loss are about 30MHz (1.25{1.28GHz), 290MHz (2.44{2.73GHz), 650MHz (3.17{ 3.82GHz) and 1130MHz (5.03{6.16GHz), covering the Compass B3, 2.5/3.5/5.5GHz WiMAX and 5.2/5.8GHz WLAN bands. Further- more, the antenna has a single-layer planar structure with a small volume of only 31 £ 21 £ 2mm 3 . Acceptable radiation patterns and peak realized gains are obtained over the operating bands.
