Shape Memory Alloys (SMA’s) have been employed to enhance structural properties and increase the ability of structures to adapt and conform as desired. Morphing technology has also proven beneficial to space hardware deployment, in addition to satellite antenna design. In this research, Reinforcement Learning is utilized with an antenna model to demonstrate that antenna elements equipped with S...

This letter presents a novel and compact antenna array suggesting geometrical modifications in the concept of collinear arrays at millimeter-wave (MMW) spectrum. The extension of the standard narrowband Franklin linear antenna array in a compact two-dimensional (2D) assembly is proposed and multiband response is accomplished in this work which fulfills demands of future 5G systems. The proposed...

A novel design of fractal using Giuseppe Peano geometry for wireless applications has been presented in this paper. Low cost FR4 glass epoxy substrate with 1.6mm thickness and dielectric constant 4.4 is used to design proposed antennas. The resonant frequency used for calculating the dimensions of proposed antenna is 4GHz. Three iterations of proposed antenna are designed to achieve the miniatu...

In this paper, the design of a coaxial feed single layer rectangular microstrip patch antenna for three different wireless communication band applications is presented. The proposed antenna is designed by using substrate Roger RT/duroid 5880 having permittivity of about 2.2 and tangent loss of 0.0009. The characteristics of the substrate are designed and to evaluate the performance of modeled a...

This paper presents the use of micro-electromechanical systems (MEMS) switches to realize the radiation pattern reconfiguration of microstrip antenna, which works in Ka-band. The antenna was fabricated on a silicon substrate and designed to reconfigure radiation pattern at the operation frequency of 35GHz. The simulation results show that by controlling the states of MEMS switches between the d...

| We examine the design of a communication link involving the data transfer from a small, low-orbit satellite to a ground station, but through a geostationary satellite. The advantage of this approach is that a single ground station , which tracks only the geostationary satellite, may be shared by a multiplicity of small satellites. Our goal is to select certain small satellite parameters { sig...

1) each satellite works with a reduced PRF given by . After the processing the AAR is the same but the RAR increases significantly (see Figure 1, left side); 2) the improvement in the final RAR can be exploited for reducing the antenna size in the along range dimension at the expenses of antenna gain. This can be balanced by increasing the averaged transmitted power by exploiting the larger pul...

This paper present a circular patch microstrip array antenna operate in KU-band (10.9GHz – 17.25GHz). The proposed circular patch array antenna will be in light weight, flexible, slim and compact unit compare with current antenna used in KU-band. The paper also presents the detail steps of designing the circular patch microstrip array antenna. An Advance Design System (ADS) software is used to ...

in this paper a new low profile substrate integrated waveguide (siw) probe-fed h-plane horn antenna structure with improved gain is proposed. the proposed antenna consists of two waveguides including a rectangular and a taper one, in which both, first and third modes of the structure are simultaneously excited leading to a uniform field distribution along the radiating aperture of the antenna a...
