“…Selective rejection and continuous tuning is obtained in [5] using varactors, suitable for vehicular communication. Slot resonators implemented on the tapered slot antenna (TSA) used to achieve frequency reconfigurability in [6, 7]. TSA with band notched function is achieved by inserting slot on the antenna in [8].…”

In this study, a dual mode antipodal Vivaldi antenna is developed to operate in ultra‐wideband and two narrowbands [global system for mobile communication (GSM) 1800, wireless local area network (WLAN)]. The antenna provides an impedance bandwidth of 9.7 GHz in wideband mode and 800 MHz, 280 MHz (WLAN, GSM 1800) in narrowband mode at −10 dB reference level. The antenna maintains symmetric radiation pattern in both the principal planes and provides minimum gain of 6 dB in both narrowband and wideband mode. Additionally, radar cross‐section performance of the antenna is calculated through simulation and discussed. Prototype antenna is fabricated with ideal switch and simulated results are validated through the measured results.
