Generally, antenna radiation patterns are measured in an anechoic condition so that the
presence of undesired reflections does not skew the final measurements. The objective of this …

We investigated the impact of window penetration loss (WinPL) on the frequency dependence
of building entry loss (BEL) from 3.5 to 24 GHz. The WinPL characteristics of an ideal …

In this paper, we describe a fixed‐beam broadband planar antenna array at millimeter‐wave
frequencies. The antenna is fed by waveguide‐feed and microstrip‐feed networks. In order …

An artificial magnetic conductor using the split‐ring resonators (SRRs) printed on conductor‐backed
dielectric substrate is presented. The simulation and measurement verify that the …

This paper presents the results of a window penetration loss (WinPL) and building entry loss
(BEL) of a traditional office building from 3.5-24 GHz. In order to investigate the factor that …

In this letter, we propose a new method to predict the field at the finite distance from a
source antenna. The Fresnel fields measured using a far-field measurement system are …

A compact duplexer for an IMT-2000 handset application is presented. To reduce its size, a
microstrip slow-wave open-loop resonator having high-impedance meander lines has been …

The small anechoic chambers built by many small‐/medium‐sized companies and universities
present difficulties in testing electrically large antennas because the chamber size cannot …

The far-field pattern and gain obtained using the far-field measurement method can be
highly accurate when the distance between the source antenna and the antenna under test (AUT) …

In this paper, we present experimental transmittance data at 0.75, 1, 2, 3, 4.5, 6, 10, 18, and
24 GHz from urban and rural environments. All measurements were performed under line-of-…
