摘要：

This paper presents a new type of turnstile antenna, realized with two crossed dipoles connected in parallel. Feeding of the dipoles in phase quadrature to obtain an omnidirectional radiation pattern is achieved by optimizing their impedances to be complex conjugates. The dipoles are realized with aluminum strips. A balun - the transition from the antenna to a coaxial cable - is accomplished with lumped parameters: two capacitors and two inductors. The concept of the turnstile antenna presented can be used in the VHF and UHF frequency ranges. The measured results show very good agreement with those obtained by simulation. The antenna is also characterized by simple manufacturing and low cost.
