摘要：Digital television broadcasting is technologies that have been developed by any country in the
world. The advantages implementations of digital television broadcasting include reception of picture and
sound sharper and better. This paper proposes a new design of spiral labyrinth microstrip antenna feed by
microstrip line with array two element for Digital Video Broadcasting Technology (DVB-T) application at
work frequency of 586 MHz. The design of spiral labyrinth is used to minimize the dimensions of microstrip
patch antenna while maintaining the working frequency at 586 MHz and array technique used to improve
gain of antenna. The proposed antenna design was originally a rectangular patch that has been modified
by the labyrinth spiral method. From the measurement result obtained return loss of -14.15 dB and VSWR
of 1.54 at working frequency of 586 MHz. Bandwidth of proposed antenna is 117 MHz
(547 MHz–664 MHz) while gain of antenna is 7.78 dBi. Beside that, using of the labyrinth spiral patch
successfully reduced the dimensions of the microstrip antenna until 62.2% compared with the conventional
rectangular patch of microstrip antenna. This study is usefull for DVB-T application in order to achieve the
maximum signal quality and picture.
