Filtering Antenna With Two-Octave Harmonic Suppression [PDF]
IEEE Antennas and Wireless Propagation Letters, 2017 A novel 2nd–order antenna with filtering performance and two-octave harmonic suppression is proposed. In order to reduce the effects of the harmonics of the antenna, two types of antennas (PIFA and patch) with different resonant characteristics are integrated into the design.

Cosynthesis of a Filtering Antenna With Harmonic Suppression [PDF]
IEEE Antennas and Wireless Propagation Letters, 2020 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 ...

Spatiotemporal phase-matching in capillary high-harmonic generation [PDF]
, 2012 We present a simple phase-matching model that takes into account the full spatiotemporal nature of capillary high-harmonic generation. Spectra predicted from the model are compared to experimental results for a number of gases and are shown to reproduce ...
