Abstract
Digital television (DTV) is an advanced technology that enables television stations to provide better pictures and sound quality. It can also offer multimedia service and great interactive capabilities. The date when television goes all digital has changed. In this thesis, we propose a compact planar monopole antenna for DTV applications on the terrestrial television broadcasting. The proposed antenna can be printed on dielectric substrate by using printed circuit board technique. Also, the proposed antenna has good feature owing to its low cost in fabrication and ease of construction. It can be easily placed into a portable device such as notebook or TV box. The proposed monopole antenna which consists of microstrip line and a patch with rectangular slits. The wideband property is achieved by using a ground plane with notch and a slotted plane on the monopole back side. These techniques are used to enhance the impedance-matching of the proposed antenna. The proposed antenna canrovide a wide operating bandwidth for DVB-T signal reception in the UHF band. The measured radiation patterns show the good characteristics in the operating frequency bands. Details of the proposed antenna designs, analysis, and experimental results of the constructed prototypes are also included.
