Summary:
To improve the polarization characteristics of thin types of printed antennas, a cross meander-line antenna was developed for receiving terrestrial TV broadcasting at UHF band. This antenna consists of two meander-line etched on both surfaces of the dielectric substrate, where the line pattern on one surface was arranged by making a right-angled turn for that on the opposite surface to receive the horizontal and vertical polarizations. According to the analyzed results, the return loss of this antenna was more than 5 dB in the frequency ranges from 500 MHz to 700 MHz and the antenna gain was larger than -3 dBi in the frequency ranges from 550 MHz to 800 MHz. From evaluation of carrier noise ratio of the analogue terrestrial broadcasting channels at UHF band, it was confirmed that the proposed cross meander-line antenna has a capability to apply into mobile and indoor terrestrial broadcasting TV antenna. The size of this antenna was 80 mm x 100 mm x 1.6 mm and it was enough small to be used for such applications.
