Defected ground structures (DGS) have been developed to improve characteristics of many
microwave devices. Although the DGS has advantages in the area of the microwave filter …

This communication presents a novel stacked multi-resonator two-layered suspended
rectangular microstrip antenna (MSA) backed by double-cavity, which yields a wide …

This paper analyses the effect of introducing multi-cavity-backing up to four cavities on a two-
layered suspended stacked one bottom four top rectangular microstrip antenna. The …

High directivity antennas are often used in communication systems to meet specific
coverage requirements. This paper presents a unidirectional, high gain UWB antenna. A …

In this paper, a TRS band (Trunked Radio System: $806 {\sim} 866\; MHz $) array antenna
has a good front-to-back ratio characteristics for the mobile communication base station is …

Mein Doktorvater Herr Prof. Dr.-Ing. Arne F. Jacob bot mir nach Abschluss meines Studiums
die Möglichkeit zur wissenschaftlichen Arbeit auf dem Gebiet der intelligenten Antennen am …

In this article, we have investigated the effect of cavity parameters such as wall height, wall
thickness, side length and air gap inside the cavity on the performance characteristics of …

In this article, we have proposed a simple model to compute the resonant frequency of a
triangular metallic cavity enclosed triangular patch antenna with variable air-gap height. The …

The effects of a cavity structure on the characteristics of a half E-shaped patch antenna
printed on a low-permittivity substrate with an air gap were investigated. The addition of the …
