This thesis presents the development of a hat-fed refector antenna with radome to be used
as satellite earth station. The antenna with self supported feed is relatively compact, circular …

We present three methods for producing lightweight waveguide-and antenna components
by autocatalytic electroless copper plating on plastics. Waveguides for the Ku-band are …

This paper describes electromagnetic modeling and experimental investigation of the
symmetrically fed log-periodic dipole antenna (LPDA) array. The array consists of two …

We present a new compact wideband multiple input multiple output (MIMO) antenna—the
double-sided 4-port arm-tapered self-grounded monopole array, briefly referred to as the …

We describe a new type of ultrawideband feed antenna based on nested coaxial
waveguides. The feed is for radio astronomy applications and covers two closely spaced …

In this paper, an 8× 1 dual-polarized linear array antenna is proposed for a random line-of-
sight over-the-air measurement system. The proposed array antenna operates over the …

A novel ultrawideband directional flat dipole capped by a planar director is proposed in this
letter. The novelty of the antenna is the great improvement of the bandwidth of a flat dipole …

Advances in astronomy are intimately linked to advances in digital signal processing (DSP).
This special issue is focused upon advances in DSP within radio astronomy. The trend …

Automotive radars are becoming more compact and affordable thanks to the rapid
development of semiconductor technology. Nowadays most vehicles are equipped with …

Formulas for calculation of aperture efficiency of a primarily-focused parabolic reflector with
a rotationally symmetric feed, or so-called Body-of-Revolution (BOR) feed, can be found in …
