A prototype of the new indoor UHF digital TV receiving
internal antenna has been designed, manufactured and tested
as shown in Fig.2. The dimensions of the new antenna are: L1
=11.5 cm, L2 = 25 cm, W1 = 8 mm, W2 =12 mm and T = 4
mm. Thus, the overall size of the new antenna is 25 x 1.2 x 0.4
= 12 cm3
. The return loss and radiation patterns of the new
antenna are numerically calculated by a software packages
that uses the moment method. They were also verified
experimentally at IMST antenna labs in Germany [6]. Fig.3
shows the return loss of the new antenna. The return loss of
the antenna is around - 8 dB over the whole band which has
more than 60% bandwidth
