Wideband, hybrid rectangular water antenna for DVB-H applications

In this article, a wideband, hybrid rectangular water antenna is proposed to cover the digital video broadcasting-handheld (DVB-H) band. The hybrid structure combines a dielectric resonator antenna (DRA) and a monopole antenna to effectively double the available bandwidth without compromising other characteristics. With a proper design, the resonance of the DRA and the resonance from the feeding probe are combined to produce a wideband response. The proposed antenna has an extremely wide bandwidth from 464 to 1017 MHz (for S11<-6 dB), or a fractional bandwidth of 74.6%. Both the computer simulations and measurements are conducted to validate the antenna performance. It is demonstrated that this new antenna is an promising candidate for DVB-H applications.
