This paper presents the improvement of rice husk ash (RHA) microwave absorber with adding carbon nanotubes (CNTs) into the composites. The electromagnetic properties of RHA and CNTs composites (RHACNTs) were measured using a rectangular waveguide (WR-62) transmission line technique with Agilent commercial software 85071E. The results show that, the additional 2 wt. % CNTs adding into the RHA composite...
Ceramic microstrip patch antenna formed using Barium Strontium Titanate (BST) has been investigated. The Computer Simulation Technology (CST) Microwave Studio is used for the simulation. We measured the gain of antennas with two, four, and six elements array of BST antenna and found that the gain of an six elements of BST array antenna was enhanced by about 2.126 dB gain over the four elements of...
A microstrip patch antenna formed from Barium Strontium Titanate (BST) ceramics has been investigated. The Computer Simulation Technology (CST) Microwave Studio is used for the simulation. We measured the gain and directivity of antennas with four, six and eight elements of BST array antenna and found that the gain of an eight elements of BST array antenna was enhanced by about 0.06 dBi of directivity...
