In this study, a compact (15 mm x 12 mm) uniplanar multi-band antenna is proposed for laptops and tablets application with a near omni-directional coverage. The main structure of the antenna implements meander design for compactness and multi-band operation. A staircase-type arm and an F-shaped arm are added for achieving resonances at exact frequencies and for good impedance matching, respectively. The antenna is designed such that it operates in all the global positioning system/wireless local area network/worldwide interoperability for microwave access bands and is easy to fabricate and integrate inside laptops/tablets. A prototype of the proposed antenna is fabricated, and its performance is validated for multi-band operation and omni-directional radiation.
