Study on Dual Wide Band Frequency Selective Surface for Different Incident Angles

This paper deals with single layer Frequency selective surface (FSS) which acts as a double band reject filter. The two stop bands are really broad with percentage bandwidth of 26.67% and 14.53%. The maximum and minimum band separation for this proposed design is around 45 dB and frequency ratio is more than 1.9.This results are almost same for different incident angles.. This design is investi...

Polarized infrared emission using frequency selective surfaces.

An emission frequency selective surface, or eFSS, is made up of a periodic arrangement of resonant antenna structures above a ground plane. By exploiting the coupling and symmetry properties of an eFSS, it is possible to introduce polarization sensitive thermal emission and, subsequently, coherent emission. Two surfaces are considered: a linearly polarized emission surface and a circularly pola...

Equivalent Circuit Model for Square Ring Slot Frequency Selective Surface

An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...

Compact Dual-passband Filter Using Spiral Resonators

A novel compact dual-band bandpass filter using spiral resonators and input/output (source-load) direct coupling structure has been presented. Two different transmission paths are utilized to realize independently controllable central frequencies and bandwidths for each passband. In addition, three transmission zeros has been introduced to improve the frequency selectivity. A dual-passband filt...

Dual-Polarized Slot-Coupled Planar Antenna With Wide Bandwidth

A new dual-polarized slot-coupled microstrip patch antenna is presented, which can achieve high-isolation low crosspolarization levels, a wide bandwidth, and low backward radiation levels. The coupling slot is an H-shaped slot. For wide bandwidth and easy integration with active circuits, it uses the slot-coupled stacked microstrip patches. The theoretical analysis is based on the finite-differ...
