A compact metasurface (MTS) antenna with a dimension of 20 mm × 20 mm consisting of non‐uniform fractional meta‐unit (n‐MTS) cells has been proposed in this article. The n‐MTS shows distinctive electromagnetic characteristics compared to conventional MTS, that is, the E‐field surface waves on the n‐MTS are singularly co‐extending in nature, exhibiting an e‐TM30 mode (e—extraordinary). The higher order modes with n‐MTS significantly improves the antenna resonant properties at (5–6) GHz Wi‐Fi band. The potential improvement in antenna modal parameters are showcased with numerical approach for validations in proximity to the theoretical quantitative metrics. A MTS antenna array configuration of dimension 40 mm × 40 mm with a RF power‐divider feeding arrangement has been proposed, operating at dual‐bands (5.45, 6.4 GHz) with radiation gain >8 dBi and radiation efficiency >80% (at dual‐bands). The unit cell n‐MTS configuration has sharp resonances and unique meta‐parameters are achieved at operating frequency, enabling existence of higher‐order mode in a low‐profile and proliferates for compact antenna design embodiment. The prototype antennas are fabricated and measured, which shows good correlation between simulation and test results, to be implemented in Wi‐Fi applications.
