The fifth generation (5G) of mobile communications givesbirth to the evolution of the base
stations. They progressively include arrays of antennas in the sub-6 GHz frequency band …

In this article, a CPW-fed flexible antenna which can work at two separate operating
frequencies is proposed. The split ring resonator structure is used to replace the …

This paper presents compact structure of bandpass filter integrated with Defected Microstrip
Structure (DMS) to produce band-pass and band reject response simultaneously. The filter …

In this proposal a frequency reconfigurable elliptical patch antenna is proposed for L and C
and application. A PIN diode with resonator is used to get the frequency switching. It has its …

This paper presents dual-band bandpass filter using defected microstrip structure (DMS).
The two DMSs was integrated with short circuit stub bandpass filter to produce high …

The design and analyses of reconfigurable dumbbell-shaped and modified H-shaped
Defected Ground Structures (DGS) in the millimeter wave band (26/28 GHz band) are …

The Minkoski Island patch antenna with complementary split ring resonator at the ground
plane are proposed in this work. At the first stage, the normal square patch antennas mainly …

This paper presents compact structure of bandstop filter with Defected Microstrip Structure
(DMS) to produce a triple-band reject response. To prove the concept of the narrow notched …

This paper presents an important review on mixer and balun designs for several UWB (ultra-
wideband) applications that generally operate in frequencies ranging from 3.1 to 10.6 GHz …

In this paper, the design and experimental characterization of a novel tunable Substrate
Integrated Waveguide (SIW) filter and tunable microstrip patch antenna in multilayer …
