Abstract :
A multimode Vivaldi antenna is presented, which is designed to operate either in a wideband mode, a wideband mode with a band rejection or a narrower passband mode. The antenna in a wideband mode is designed to have a bandwidth of 2-8 GHz. In the notch band mode, the antenna has tunable narrow band rejection between 5.2 and 5.7 GHz. The Vivaldi antenna can also operate in a narrow passband mode, which has a bandwidth of 4.6-5.0 or 5.3-5.6 GHz. Other narrow passbands at 3.6, 3.9 and 6.5 GHz can also be selected. Measured and simulated results are presented.
