Wideband transitions are designed and analysed by using two different approaches of the
finite‐difference time‐domain (FDTD) method, in combination with the theory of nonuniform …

This study investigates the application of Rotman lens antennas in the near field. The design
equations of these antennas have been derived in the near field and demonstrated to be …

This article proposes a new impedance matching method to provide an energy transformer
between 50 Ω beam ports and the cavity of a Rotman lens. The model is derived from a …

The Rotman lens is a multi-input device which controls the beam scan angle, depending on
the phase shift corresponding to the path length between the input source positions and the …

The mathematical model of the near-field-focused Rotman lens is given in Fig. 1. The two-
dimensional coordinate system (x, y) centered at O 1 and the coordinate system (X, Y) …

Correct estimation of the phase centers of the input and output ports is important in Rotman‐
type bootlace lens applications. Any shift in the position of the phase center of a port used as …

Allocating multiple beams in desired angles is a cornerstone component in modern wireless
systems. Scanning in microwave lens is independent of phase coupler and phase shifter …

A method has been introduced for determining the phase center of two dimensional
radiators. This method involves the determination of the phase errors against the angle at …
