In this paper, microstrip dual band antenna array with defected ground structure has been proposed for low frequency wearable on-body applications. The simulated Cotton, Polyimide, Polyester and Teflon (PTFE) flexible materials which are mostly used biomedical performance of 2x2 trapezoidal patch partial ground, thin slot defection at center studied in terms return loss, VSWR, power handling ca...

Various complementary split ring resonators (CSRRs) are used as defected ground structures (DGSs) in the bandpass filter (BPF) design for different communication applications. In this paper, a hybrid CSRR has been introduced as a DGS in the ground plane of a dual-mode microstrip BPF to produce a new compact filter with dual band response. The proposed CSRR structure is essentially based on the ...

In this proposal new trapezoidal patch microstrip feed antenna array with ground defected by square shape is designed for detailed parameter study in terms of return loss, VSWR, gain and radiation pattern S band applications from 2 to 3 GHz. The bandwidth properties four radiating element arranged x has been improved defecting half the etching opposite vertical point. 30 70 1.6 mm dimension str...

A microstrip patch antenna is designed that have metallic ring coplanar to radiation patch and defected ground structure to enhance the gain is proposed. The design forces conversion of the surface wave energy into the space wave energy by the scattering of surface waves from metallic ring. The metallic ring is placed around the metal patch at a distance of d1 from the edges of the metal patch ...

In this communication, the design and analyses of novel printed ultra wide band ring monopole antenna is presented. The recommended has a pretty small size 20 x 26 1.6 mm3 which on FR4 dielectric material constant 4.4 ad loss tangent 0.02. general geometry radiating part composed circular ring. defected ground structure corner points. feed placed in asymmetrical position with respect to x-axis ...

This paper discusses the design, simulation, and realization of a leaky-wave microstrip antenna with multiple slots defected ground structure (DGS). The DGS was designed to operate at 5.925-6,425 GHz for wireless local area network applications (WLANs), gain ≥4dBi. uses FR-4 epoxy as substrate dielectric constant 4.6 thickness 1.6 mm. has dimensions 45.1 mm × 24.8 mm, while 40.6 25 simulation r...
