Multimode and Multiband Microstrip Antennas [PDF]

open access: yes, 2007
This thesis describes original work on the broadband and multiband matching of microstrip patch antennas. Microstrip patch antennas suffer from many constraints on their performance. One major restriction is their narrow impedance bandwidth.

The Iseult Coil, a Hybrid RF Coil for the First Human Brain Images at 11.7 T: Receive Performance Comparison With a Twin Coil at 7 T. [PDF]

open access: yesNMR Biomed
Our 8‐Tx/32‐Rx coil is based on two rows of transceiver microstrips intertwined with receive‐only loops. Comparison of the intrinsic SNR at 7 and 11.7 T leads to a 2.2 ratio for the human brain, and 2.75 for a 16‐cm agar sphere, translating into α = 1.5 and 1.95 in the B0α$$ {B}_0^{\alpha } $$‐SNR model, respectively.

Microstrip dual-bandpass filter design

open access: yes2017 25th Signal Processing and Communications Applications Conference (SIU), 2017
Dual-bandpass microstrip filter design is suggested for small-scale device. Design of dual-bandpass microstrip filter has been created with concentric square structure by using microstrip resonator. Both of resonators have been used to get dual-bandpass frequencies and fed with only one source.

Design of tunable microstrip bandstop filter

open access: yes2016 Asia-Pacific Microwave Conference (APMC), 2016
In this paper, a novel microstrip bandstop filter with tunable center frequency and bandwidth is introduced. A dual-mode square loop resonator and three varactor diodes are used to achieve the tunability operation. The dual-mode square loop resonator is coupled to a straight transmission line that connects input and output ports.

Dual-mode microstrip bandstop filters

open access: yes2008 Asia-Pacific Microwave Conference, 2008
In this study, we proposed a novel bandstop filter using a square loop resonator. Dual-mode microstrip bandstop filters are designed and realized by employing two degenerate modes of a dual-mode microstrip square loop resonators. Microstrip loop resonators have been used extensively for bandpass filter applications.

Hybrid Microstrip/Slotline Ultra-Wideband Bandpass Filter with a Controllable Notch Band

open access: yesInternational Journal of Antennas and Propagation, 2017
An ultra-wideband (UWB) bandpass filter (BPF) with a controllable notch band is presented by using hybrid microstrip/slotline structure. Firstly, a slotline resonator with symmetrically loaded stubs is fed by two microstrip lines to produce a UWB ...

The microstrip wideband filter

open access: yesIOP Conference Series: Materials Science and Engineering, 2016
The filter of high frequency-selective properties is developed. The central six-mode resonator of the design which can be used in the aerospace equipment is electromagnetically connected with six single-mode resonators. The good agreement of the calculated data in comparison with the data received on the experimental model of a design is shown.
