Fig. 6From: A flower bud-shaped flexible UWB antenna for healthcare applicationsPhotograph of anechoic chamber set up. An anechoic chamber is used to measure the antenna radiation pattern, as seen in this figure. The antenna radiation is measured with the help of an anechoic chamber of size 7.5 m × 5 m × 3.3 m. The antenna is set up for far-field measurement over the distance of 5 m for the antenna under test (AUT) and the reference antenna. This anechoic chamber provides effective shielding and allows an interference-free testing environmentBack to article page
