Abstract

A simple internal antenna that combines a planar inverted F antenna (PIFA) and a loop antenna to achieve wideband (BW ∼ 48%) operation in ultra-high frequency (UHF: 470-771 MHz) band for digital television (DTV) applications is presented. The design allows the installation of an antenna within a TV model, thereby addressing the limitations of space. The 49-inch DTV is used for the practical implementation experiment. The TV bezel (made of polycarbonateacrylonitrile butadiene styrene (PC-ABS): ϵr = 3.5; tan δ = 0.005) is used as the substrate for the antenna design. The antenna is placed on the top edge of the TV model. With the combination of the PIFA mode and loop mode operations, the operating bandwidth of the proposed PIFA-loop antenna is significantly broadened. The measured results show that the proposed antenna has wide bandwidth of about 410 MHz (460-870 MHz) and suitable radiation performance with higher than 2.2 dBi of peak gain and 47% of efficiency within the operating bandwidth.
