The purpose of this paper is to design and fabrication of an annular ring slot patch antenna with short stub (ARSPA) for mobile applications Digital Cellular System (DCS) (1.711.88) GHz, Personal Cellular System (PCS) (1.85 -1.99) GHz, and Universal Mobile Telecommunications System (UMTS) (1.71-2.17) GHz. Return loss and bandwidth are studied with respect to short stub location. By using short ...

After publication of this work [1], we noted that we inadvertently failed to include the complete list of all coau-thors. The full list of authors has now been added and the Authors' contributions and Competing interests section modified accordingly. Authors' contributions SJK prepared for the manuscript and study coordination; IPH prepared for building up the experimental environment and execu...

A planar phase gradient metasurface (PGM) with gradients in two in-plane directions will introduce additional wave vectors to the reflected vector. For small incident angles, close normal vector, magnitude of vector is smaller than that and direction anomalous can be determined from components components. The expanded generalized Snell’s law, which includes diffraction order modes, combined arr...

A combination of lowpass and dual band bandpass filter with improved selectivity is presented in this manuscript. Two circular split ring resonators which are connected at the upper side, provide a characteristics. In order to achieve combined passband response two L-shape stubs incorporated into structure. The parametric analysis proposed has been carried out using CST microwave studio. numeri...

For a typical frequency modulated continuous wave automotive radar system, design using novel leaky-wave antenna is proposed that has simple, cheap and easy manufacturing structure whose performance compared with two different arrays. The software used were MATLAB CST Microwave Studio. first system was an inset-fed patch array, the second circular array Buttler beamforming network as beam scann...

The objective of this paper is to design a parasitic antenna array capable rejecting interfering signals and directing its main lobe towards the wanted signal. designed linear consisting an active monopole fourteen monopoles. method used LMS, making it possible calculate values reactive loads be connected ports elements so that radiation patterns satisfies fixed constraints. simulation results ...

in this paper, a novel directional super wide band micro strip antenna based on a simple and new geometry has been proposed. the antenna exhibits the widest bandwidth ever reported to the authors’ knowledge from 50 ghz to 200 ghz. its radiation pattern is approximately steady in the frequency ranges of 50 ghz to 200 ghz. the antenna consists of a club-like radiating patch, a combination of thre...

One of the most challenging works on compact antenna design is to maintain flexibility orientation. This paper demonstrates a coplanar waveguide (CPW) fed monopole with rubber substrate at 2.45 GHz center frequency for ISM band application. The proposed attained realized gain 4.06 dB radiation efficiency around 90% peak value and bandwidth 541.5 MHz. was designed using CPW structure. CST microw...

U-slot patch antenna design and implementation are discussed in this paper for 5.5GHz WLAN use. The VSWR S11 of suggested construction, which is based on FDTD techniques to attain the desired specification, computed using Computer Simulation Technology (CST) microwave studio. maximum bandwidth while utilizing coaxial feed 260 MHz, corresponds frequency range 5.36-5.62 GHz, at its center resonan...
