Abstract
In the past decade, the rapid improvement in wireless communication system has motivated extended research on low profile, compact and cost effective circularly polarised wideband patch antenna. A flexible and new design of wideband circularly polarised antenna finds application of WLAN. The proposed CP wide band antenna contains a rectangular radiating patch with slots on the opposite sides of the patch to achieve CP and the o-shaped semi-circle with squares inscribed to get wide band with truncated ground to achieve two resonating frequencies on little cost FR4-substrate bear thickness of 1.6 mm. The proposed final design of the antenna is resonating at frequencies 4 GHz and 5 GHz respectively with good impedance matching values of -37.44 dB and -49.72 dB. The propose structure is maintaining its VSWR at the respective bands from 1-2 with antenna gain around 2.5 dBi. The main objective of this article is to achieve the wide bandwidth and circular polarisation with minimal interferences.
