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 defected ground structure to excite the CP property, simultaneously realizing compactness.It offers a 50.

5% reduced patch area compared to a conventional design.Novel stubs and slot shapes are integrated in the transmission line to reduce higher (up to the third) order harmonics.The proposed prototype yields a -10 dB reflection coefficient (S11) impedance bandwidth of 12.

53%, a 3 dB axial apac1/60/1/cw ratio bandwidth of 3.27%, and a gain of 5.64 dBi.

Measurements also show good agreement with simulations.
