A Transplantable Frequency Selective Metasurface for High-Order Harmonic Suppression
A transplantable frequency selective metasurface element (FSMSE) for high-order harmonic suppression (HS) is presented in this paper. The proposed harmonic free FSMSE can be integrated with arbitrary frequency selective surfaces (FSSs) operating at the ...

Cosynthesis of a Filtering Antenna With Harmonic Suppression [PDF]
To suppress the undesired signals at the front-ends of wireless systems, a co-design of a simple filtering antenna highly integrated with a slotline-based network is presented and studied in this letter. The proposed antenna integrated with the low-pass filter, the bandpass response is achieved and impedance bandwidth is also enlarged due to the ...
