AB - This paper proposes a small‐sized field‐effect transistor (FET) based active integrated antenna (AIA) for terrestrial digital multimedia broadcasting (T‐DMB) signal reception, which is one of the mobile TV services allocated to 200 MHz band. The commercially used T‐DMB antenna is a 120 mm long monopole, but the size of the proposed one is reduced to 50 mm by the method of active device integration. The active device integrated to the radiator influences not only on the current distribution at the radiator but also the input impedance, results in an antenna size reduction with an enhanced gain. In addition to this, a band‐pass filter is designed at the input port of the radiator. This plays a role as a matching circuit between a radiator and an active device as well as provides a band‐selection function simultaneously to be free of other high intensity signals existing around the T‐DMB band. The antenna effective length related to the same‐sized monopole and noise figure are measured to verify the validity of the proposed antenna. The performance of the proposed FET based AIA shows the feasibility of designing absolutely small‐sized antenna with active devices integrated compared to an operating frequency band. © 2007 Wiley Periodicals, Inc.
