Use of discontinuities in ground planes or in micro strip lines is currently employed to
improve the performance of different passive circuits. It includes size reduction of amplifiers …

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 …

A compact phase shifter using reconfigurable defected microstrip structure (RDMS) is
proposed for phased array antennas. A complete phase shifter design scheme that serves …

In this work, the introduction of Defected Microstrip Structures and Defected Ground
Structures is presented to improve the performance of a traditional stepped-impedance …

This work is regarding the development of a novel antenna called optically controlled
reconfigurable filtenna, which is based on the integration of a broadband printed antenna …

In this article, a suggested design of mirror stairs microstrip antenna that has a planar
geometry with defected structures is presented for multiband applications. The suggested …

A new technique is employed to reduce the size of Yagi-Uda antennas. The technique
consists of adding short circuited cylindrical covers to the structure, making the elements be …

ABSTRACT A microstrip patch antenna for Wi-Max and GSM application is proposed. The
antenna has a frequency bandwidth of 1.24 GHz (4.6053 GHz–5.8481 GHz) for WLAN and …

This article demonstrates novel ideas for mitigation of far‐end as well as near‐end crosstalk
in coupled pair microstrip lines (CPMLs) by means of defected microstrip structure (DMS) …

In this article, two cascaded defected microstrip structures (CDMSs) are proposed to
increase the effective inductance. So the cutoff frequencies of filters made by CDMSs can be …
