Novel dual‐band dual‐prototype bandpass filter

open access: yesMicrowave and Optical Technology Letters, 2014
ABSTRACTThis article presents the novel dual‐band dual‐prototype bandpass filter. The corresponding lowpass prototypes of the first and second passbands of the proposed filter are controllable and can be specified to be different at the outset. The dual‐band resonator is realized by trisection stepped‐impedance resonator.

Dual-band Sierpinski fractal monopole antenna [PDF]

open access: yes, 2000
A new top-loaded reduced-sized dual-band (1.9 GHz and 3.5 GHz) monopole antenna for wireless communications is presented. The antenna provides better than -15 dB input return loss and keeps the same radiation pattern over both bands.

Design of Integrated Duplexing and Multi-Band Filtering Slot Antennas

open access: yesIEEE Access, 2020
In this paper, a duplexing antenna and two multi-band filtering antennas using resonator loaded slot are presented. The loaded slot can be flexibly designed as a dual-band or a tri-band antenna by changing the number of the loaded resonator.

Dual-Band, Dual-Linearly Polarized Transmitarrays for SATCOM Applications at Ka-Band

open access: yes2022 16th European Conference on Antennas and Propagation (EuCAP), 2022
We propose here a 40×40-element sharedaperture dual-band dual linearly-polarized transmitarray with 1-bit phase resolution and fixed beam at Ka-band. The design is based on a stacked approach where the unit-cell size is compact and is equal to only 0.48×$\lambda_0$λ and 0.32×$\lambda_0$ at 29 GHz and 19 GHz, respectively. The beam-scanning performances
