In this paper, a novel microstrip structure is developed to realize a dual-band bandpass filter. The proposed bandpass structure uses a microstrip resonator with two independently controlled resonance frequencies producing two frequency bands of interest controlled by adjusting the dimensions of the resonator. Parametric analysis is performed on the structure to determine the optimum dimensions...

In this paper two linear arrays including a linear 1×4 and a planar 2×2 of microstrip patch and half-mode substrate integrated waveguide (SIW) cavity hybrid antenna are introduced and investigated.

To achieve dual frequency operation for wireless body area network (WBAN) applications, a hybrid dual-band dielectric resonator antenna with serpentine slot fed by a microstrip line is proposed. The proposed antenna structure consists of cylindrical dielectric resonator and serpentine slot resonator. The serpentine slot is etched on the ground plane of the dielectric resonator antenna (DRA). By...

RF and microwave bandpass filters are key components for most of the recent communication systems. A conventional hairpin-line resonator size is normally very large. A Multi-folded hairpin line resonator filter helps to reduce the size, if the required selectivity characterstrics are not critical. This paper presents the design, simulation, optimization and test results of a new class of a 4-po...

A method for increasing the bandwidth of microstrip array antenna by adding additional resonator, which is directly – coupled to the non – radiating edges of a radiating element is narrated. The experimental result of four elements non-radiating edge directly – coupled rectangular microstrip array antenna (FNCRMAA) shows wide band with bandwidth of 15.63 %. Further extending the elements of arr...
