Dual-band VHF/UHF smartphone antenna for mobile digital television

A dual-band VHF/UHF antenna suitable for use with a portable media device is proposed. The antenna is designed to attach to a smartphone or tablet as a folding cover. It uses a capacitively-coupled element for the VHF antenna and a shorted dipole for the UHF antenna. A low-pass filter network couples the two antennas together so they can be fed from a single port. Applications of the antenna are for the reception of mobile digital television signals such as the ATSC M/H standards or DVB-H on portable media devices such as smartphones or tablets.
