Co-planar Waveguide Circular Ring Microstrip Patch Antenna for WLAN Applications

Meenal Kate, Anjana Goen



A printed circular microstrip patch antenna with a four rectangular shape strip and co planar rectangular ground plane has been proposed. Four rectangles of dimensions 4.8mm x3mm are arranged in such a manner to achieve both the WLAN frequency band. The bandwidths of 341MHz and 414MHz are achieved having a resonant frequency of 2.37GHz and 5.45GHz respectively. This antenna is printed on the glass epoxy (FR4 lossy) of dielectric substrate with relative permittivity (€r) of 4.3, thickness of 1.6 mm. Other parameters such as directivity, antenna gain, radiation pattern are also analysed with different values of ground plane length. The proposed antenna simulation result is capable of operating over the 2.187–2.527 GHz frequency band and 5.234-5.643 GHz frequency band, which cover the 2.4/5.2GHz, WLAN operating bands.
