Abstract

In this paper, a planar sleeve monopole antenna for indoor digital TV reception is presented. The antenna has broadband property with the planar monopole and ground of sleeve. Sleeve monopole and ground conductors of the antenna are on the same plane, and exited through CPW feeding. Sleeve monopole and ground of proposed antenna exist on coplanar plane, and excite as CPW. It used FR4 epoxy dielectric substrate of ${\varepsilon}r=4.4$, and the size is $20[mm]{\times}170[mm]{\times}1.6[mm]$ dimension. So the internal antenna is suitable. The measurement results of the fabricated antenna, return loss is larger than -10 [dB] in 470~806 [MHz]. Maximum gain is 0.59 [dBi] on E-plane at 810 MHz and 1.70 [dBi] on H-plane at 640 [MHz]. Radiation pattern is about the same that of dipole antenna at all frequency.
