Reconfigurable 3D folded monopole antenna design for DVB-H applications

A frequency tunable compact 3D folded monopole antenna designed for DVB-H applications is presented. By loading the folded monopole antenna with a variable capacitor, the operating frequency of the antenna can be continuously tuned over the frequency range of the DVB-H standard, from 470 MHz to 862 MHz. Furthermore, a water layer is loaded to reduce the dimensions of the antenna while keeping a reasonable bandwidth for DVB-H specifications. The antenna element occupies a very small volume 17.5 mm × 7 mm × 3 mm (probably the smallest reported volume for DVB-H applications), thus it is a very promising candidate for DVB-H applications.
