Compact circularly polarized truncated square ring slot antenna with suppressed higher resonances.
This paper presents a compact circularly polarized (CP) antenna with sophie allport bee curtains an integrated higher order harmonic rejection filter.The proposed design operates within the ISM band of 2.32 GHz- 2.63 GHz and is suitable for example for wireless power transfer applications.Asymmetrical truncated edges on a square ring create a defec
