Abstract :
A novel dual-polarized broadband horn antenna working at 75-500 MHz with coaxial input feed section is investigated. Some new structures are introduced to support the huge dimensions and reduce the weight based on the precondition that the effect of these solutions to the low end performance is minimization. And an adjustable shorting plate is inserted on the bottom of the horn antenna to improve the return loss performance. Details of the horn antenna design and experimental results are presented and discussed.
