Some focusing properties of Fresnel zone plate (FZP) lens antennas in the near-field region
are presented at the ka-band. Simulated and measured results of the FZP antenna show …

In this paper, we propose an optimal design procedure for the focused antenna array based
on the maximization of power transmission efficiency between two antennas. In the …

A new concept in designing large array antennas to focus the microwave power in the
radiation near-field region is presented. A small focused array antenna using microstrip …

A microstrip planar array antenna is presented in this paper, which is designed to have near-
field focused beams, and it is capable of steering its focus on the designed focal plane. The …

This paper presents a 2-D near-field focusing (NFF) substrate-integrated-waveguide (SIW)
leaky-wave antenna (LWA) array with high radiation efficiency. In most of the existing 2-D …

An microstrip planar array antenna with near-field focused beams is presented in this paper,
whose elements are series fed in both E-and H-planes. The focus is designed at a distance …

A microstrip array antenna with near-field focused beam is presented in this paper, which is
composed of eight series-fed and frequency-scanned linear arrays. The array focus can be …

Focusing antennas are of interest in many application including microwave wireless power
transmission, remote (non-contact) sensing, and medical applications. Different kinds of …

The spot of near-field Fresnel zone plate (NFFZP) is very important in electromagnetic field.
In this paper, an NFFZP which has been designed to focus a spherical wave at a spot is …
