An internal modified rectangular loop antenna with two open stubs for digital video broadcasting‐handheld (DVB‐H) terminals is proposed. The antenna consists of the modified rectangular loop, the two open stubs, and a four element matching. We have used the meandering technique to increase the electrical length of the antenna and two open stubs for tuning the high frequency edge of the DVB‐H band. To more improve the impedance bandwidth of the DVB‐H frequency band (470–702 MHz), a four element matching circuit is used. All simulations are carried out by Ansoft HFSS software. Moreover, by fabricating the antenna, the simulations results are verified by experimental data. Good antenna performances such as radiations patterns and antenna gains over the operating frequency band have been observed.
