Multimode and Multiband Microstrip Antennas [PDF]
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.

Microstrip antennas utilizing MEMS for reconfigurable polarisation states [PDF]
A modern approach to an established technique is investigated for the electronic control of polarisation of microstrip patch antennas. The control is achieved by placing micro-electromechanical switches (MEMS) at appropriate locations in a patch ...

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]
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
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.

Dual-mode microstrip bandstop filters
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.

Design of tunable microstrip bandstop filter
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.
