Modern day systems often require reconfigurability in the operating parameters of the transmit and receive antennas, such as the resonant frequency, radiation pattern, impedance, or polarization. In this work a novel approach to antenna reconfigurability is presented by integrating antennas with the ancient art of origami. The proposed antenna consists of an inkjet printed center-fed spiral ant...

A compact semi-hexagonal-shaped MIMO antenna loaded with a planar SRR (split-ring resonator) structure is presented for Terahertz applications. The single radiating element consists of semi-hexagonal shape metallic patch SRR-CC (Split ring Resonator-Connected C shape) metamaterial unit cell to enhance the impedance bandwidth as well gain proposed antenna. can be easily extended into two-port an...

The wearable textile antenna plays a decisive role in the currently increasingly wireless communication network area. To realize miniaturization and electromagnetic reliability, slotted full-textile microstrip was designed fabricated using screen printing method. measured return loss radiation pattern were tested compared with simulated results. Additionally, adhesion between silver paste coati...

In this study, we describe the design and fabrication of an N-way calibration line for active electronically scanned array radar. The designed consisted open-ended probe a Wilkinson power divider. It was to calibrate by measuring amplitude phase transmit/receive path. addition, signals from antenna module could be transmitted assembly using A multilayer printed circuit board (PCB) used miniatur...

in this paper a new uwb textile slot antenna has been designed with high precision. this work aimed to makecloser steps towards real wearability by investigating the possibilities of designing wearable uwb antenna wheretextile materials are used for the substrate as well as the conducting parts of the designed antenna. the antenna iscomposed of three textile layers: the top and bottom are condu...

In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber without disturbing the antenna performance. The simulations show that radar cross section of simulated antenna is reduced in a wide frequency ...

in this article, the linear array (with 20 elements in the horizontal orientation) of microstrip antenna is examined with horizontal polarization. the set includes three microstrip substrates. there is a power network in two lower substrates and microstrip patches in the upper substrate. excitation of patches has been done as coupled through the power network in two lower substrates. using the ...
