Abstract

A compact Asymmetric Coplanar Strip (ACS) fed planar monopole antenna suitable for 5.2/5.8 GHz WLAN and ISM applications is developed and discussed. Developed radiator possesses an enhanced gain and directional radiation pattern without any additional parasitic elements. Overall dimension of the antenna is 20 × 9.1 × 1.6 mm3 when fabricated on an FR4 substrate having relative permittivity of 4.4, which is very compact when compared to other directional monopoles. The gain enhancement and directivity of the antenna is obtained without the help of any additional parasitic/reflective elements. Equivalent circuit modeling and FDTD analysis of the structure were also performed and the results obtained are compared with measured results. Compact Structure, Enhanced directivity and gain, minimum design parameters, stable and reliable radiation pattern and polarization, and high efficiency make this structure a potential candidate for upcoming high data rate 5G communication applications in ISM and WLAN field.
