摘要
This paper presents a novel asymmetric coplanar waveguide-fed quad-band hybrid antenna for wireless applications. The proposed hybrid antenna combines a conventional monopole antenna and a zeroth-order resonator antenna to perform a dual-mode operation. The first mode is generated by a slotted monopole antenna, supporting the two higher resonances at about 3.5 and 5.8 GHz. The second mode is supported by loading a composite right-/left-handed transmission line unit cell near the slotted monopole, contributing to the two lower resonances at about 1.6 and 2.5 GHz. It is printed on an FR4 substrate with the overall dimensions of 40 mm x 24 mm x 1.6 mm. Experimental results demonstrate that it can cover the global positioning system (1.57-1.59 GHz), wireless local area network (2.4-2.485, 5.15-5.35, and 5.725-5.825 GHz), and worldwide interoperability for microwave access (2.5-2.69, 3.3-3.7, and 5.25-5.85 GHz) applications with monopole-like radiation patterns and acceptable gains.
