IEEE Transactions on Antennas and Propagation, 2014
In this paper, a beam-steering antenna array that employs a new type of reconfigurable phase shifter is presented. The phase shifter consists of a number of cascaded reconfigurable defected microstrip structure (DMS) units. Each DMS unit is made by etching a slot in a microstrip line and loading the slot with PIN diodes.

Abstract In this article, a compact bandstop filter (BSF) with desirable four attenuation narrow bands is developed for multiple wireless network systems. The developed filter composes of two microstrip circuits. In the first microstrip circuit, stepped-impedance and two open-circuit stubs in defected microstrip structure (DMS) are analyzed to ...

Multi-band bandstop filter using inner T-shaped defected microstrip structure (DMS)
AEU - International Journal of Electronics and Communications, 2014Abstract In this paper, inner T-shaped defected microstrip structure (DMS) is studied, and new bandstop filters with a single band, dual-band and tri-band are developed. The new designs have adjustable multi-band operation and simple circuit topologies, and the symmetrical periodic T-shaped DMS introduces transmission zeros which improve the filter ...

A proposed defected microstrip structure (DMS) behavior for reducing rectangular patch antenna size
Microwave and Optical Technology Letters, 2004AbstractA defected microstrip structure (DMS) is proposed to reducing the size of a rectangular patch antenna by increasing its electric length, without degrading its performance. To illustrate this advantage, one conventional and one proposed defected patch antenna were developed and measured at 1.77 GHz.

2009 First Conference on Millimeter-Wave and Terahertz Technologies (MMWaTT), 2009
This paper presents novel millimeter wave filter structures by creation of some slots on the strip. These slots perform a serious LC resonance property in certain frequency and suppress the spurious signals. In high frequencies and high density applications, the board area is seriously limited, so using these filters; the circuit area is minimized. The
