We present a cylindrical dual-polarization phased array antenna for weather surveillance radars that features high isolation, matched copolar beams, low sidelobe levels, and adaptive null steering. crossed dipole element to replace the patch on currently deployed polarimetric radar (CPPAR). The offers suppressed surface wave lower coupling between adjacent elements of an array. As result, we ac...

In this paper, we investigate and compare two different antenna types for UHF SATCOM applications; proposed Moxon type (bent dipole) and conventional egg beater (loop) antennas in terms of antenna performance and physical size. Bent dipole and egg beater antennas are simulated using HFSS software. Prototype antenna for Moxon type is also fabricated and measured for its return loss using Agilent...

A folded loop antenna for handsets has already been introduced and shown as one of balanced feed antennas for handsets, which is very effective to mitigate the antenna performance degradation due to the body effect. In addition, to be lower profile of folded loop antenna, Built-in folded dipole antenna, which has a structure folded loop elements sideway so that the antenna can be placed on the ...

A novel localization method based on multiple signal classification (MUSIC) algorithm is proposed for positioning an electric dipole source in a confined underwater environment by using electric dipole-receiving antenna array. In this method, the boundary element method (BEM) is introduced to analyze the boundary of the confined region by use of a matrix equation. The voltage of each dipole pai...

This article reports on an intercomparison study the effect of incidence angle spatial average incident power density (PD) and resultant temperature rise using computational thermographic measurement approaches. Two definitions PD—the peak spatial-average normal component Poynting vector norm vector—were compared. First, PD in a layered skin model was conducted for 4 × dipole array antenna. The...

For an RF system, a high-gain antenna helps to improve the equivalent isotropic radiated power (EIRP) of transmitter and end-fire array directivity (D) half beam width (HP) antenna. This work presents new simple design method for design. The states that when elements are λ/2 apart, could be designed constructed easily without matching networks between elements. Utilizing Rogers 4350 PCB technol...
