This paper presents a comparative study on the effect of the polymer dielectric and magneto-dielectric substrates in antenna array. A 1×2 multilayer antenna array based on polymer magneto-dielectric (PDMS-Fe3O4) composite substrate have been designed and fabricated to evaluate the contribution of such substrate materials in antenna array performance and characteristics. The proposed antenna was compared...
In this paper, polymer magneto-dielectric (PDMS-Fe3O4) is proposed as a new substrate for multilayer microstrip antenna array for enhancement of bandwidth, gain, and overall efficiency. Nanoparticles of iron oxide (Fe3O4) have been composited with polymer matrix of polydimethylsiloxane (PDMS) to build up the polymer magneto-dielectric layer (PDMS-Fe3O4). Polymer magneto-dielectric (PDMS-Fe3O4) layer...
A high gain reconfigurable narrow beam steering array (RNBSA) antenna with Micro-Electro-Mechanical-System (MEMS) is presented in this paper. The RNBSA antenna is implemented a probe coupling feed technique to supply the energy to the radiating elements from the source and vice versa. At the same time, the MEMS circuits are integrated on the transmission line of the RNBSA antenna as the RF switches...
A high gain 5.8 GHz multiple input multiple output (MIMO) 2×2 Array antenna with dimension of 58 × 110 mm2 is proposed in this paper. The proposed design is composed of two sets of four elements antenna array. Each element is constructed from four truncated arrays radiating elements which capable to achieve circular polarized capability. The antenna is fed by two coaxial feeds with full ground plane...
Radial Line Slot Array Antenna is a slot planar antenna. The slot has been arranged in radials to create a concentration of wave into a single point. The body of this antenna normally a metal with hollow cavity and slots. However, recent development on RLSA has utilized the FR4 as a substrate material. The copper is attached to the substrate and the slot is not hollow as compare to the conventional...
This paper introduces the performance of an elliptical shaped antenna with random slots and compares the results between the original patch and the patch without dots. 5.8GHz is the reference or desired frequency set for measuring the performance of this antenna. For the design, three elliptical shaped slots with different dimensions are deployed and connected to each other acting as a main radiating...
