Abstract :
A broadband VHF-UHF end-fire Yagi-Uda array is proposed for possible air vehicle integration and operation within the 240-465 MHz frequency band. The array consists of a driven dipole, a reflecting dipole, and three directing dipoles. The broadband impedance, pattern, and gain responses are obtained by adding two parasitic metal strips adjacent to a fat driven strip dipole. The array has a peak gain greater than 7 dBi and Forward to Backward ratio (F/B) greater than 13 dB throughout most of the operating frequency band.
