Hexagonal Shaped Body Wearable Textile Antenna on EBG Substrate Material

In this paper, a hexagonal shape wearable antenna is presented .the proposed antenna is having EBG structure embed in the inner substrate layer. The antenna resonates at 2.45 GHz. When antenna is incorporated with EBG cell structure, it shows improvement in gain by 1.9 dB and 33% bandwidth improvement. The EBG structure consists of just a 3x3 elements but reduces backward radiations considerabl...

Influence of optical Kerr coefficient on photonic band structures of hexagonal-lattice function photonic crystals

In this paper, we have studied the photonic band structure of function photonic crystals in which the dielectric constant of the scattering centers (rods) is a function of space coordinates. The under-studied lattice is hexagonal and cross section of rods has a circular symmetry embedded in the air background. Photonic band structures for both electric and magnetic polarizations of the electrom...

Study of RFQ Accelerating Structures Based on Multi-conductor Resonators

Microstrip Dual-Band Bandpass Filter Using U-Shaped Resonators

Coupled resonators are widely used in the design of filters with dual-passband responses. In this paper, we present a dual-band bandpass filter using only couplings between adjacent resonators without cross-couplings. The dual-band bandpass filter with centre frequencies of 1747MHz and 1879MHz respectively is designed and fabricated using microstrip U-shaped resonators. Using the coupled resona...

On the Design of Compact Dual Mode Multi-Band Bandpass Filters using Triangular, Circular and Hexagonal Shape Open – Loop Resonators

The design and performance of a band pass filter for UWB communications is presented in this paper. Open loop resonators consisting of parallel arms (stubs) protruding from a 50Ω transmission line create the required rejection bands. The arms height, width and spacing control the bandwidth achieved by the filter. Each pair of arm creates one reject band in the transmission response. Three filte...
