A novel double-higher-order entire-domain volume integral equation (VIE) technique for efficient analysis of electromagnetic structures with continuously inhomogeneous dielectric materials is presented. The technique takes advantage of large curved hexahedral discretization elements—enabled by double-higher-order modeling (higher-order modeling of both the geometry and the current)—in applicati...

Multiple input multiple output antenna is the key technology which enables design of 5G networks. In order to achieve desired beam forming and side lobe reduction capabilities, antennas used in MIMO are required feed with signals having different phase amplitude. It possible variable shift attenuation using shifter amplitude limiters. However when these devices between source antenna, they make...

The conventional series-fed endfire dipole antenna has a wide impedance bandwidth and is inexpensive to manufacture. However, it disadvantage: its size large because of the inter-dipole spacing, which required satisfy condition for good radiation characteristics. Here, we propose two-dipole with reduced size. miniaturized was designed using meander line reduce interdipole spacing while ensuring...

A low-cost method to 3D print and metalize circular waveguide components is demonstrated using polylactic acid (PLA) aluminum adhesive backed tape. gradient index (GRIN) lens, an externally metalized thin-walled conical horn, a WR90 rectangular linearly polarized transition are simulated, fabricated, measured. The horn lens were both monolithic prints that metallized simplify the metallization ...

This letter introduces a technique for the power density (PD) pattern measurement in near field taking into account antenna/body coupling at millimeter waves (mmW). The proposed method employs specifically designed structure reproducing reflection coefficient from human skin. is optimized to convert absorbed PD an infrared (IR) pattern, remotely recorded using high-resolution IR camera reconstr...
