Abstract :
This paper presents a new collinear antenna array that can realize high omnidirectional gain at 30GHz band. The array are formed by two stacked biconical antenna elements fed parallel through a balun, and each element can produce an omnidirectional gain of around 9.5dBi. The measured ™10-dB impedance bandwidth of the antenna is 26.2-30.2GHz. Within the bandwidth, the antenna achieves a high measured omnidirectional gain of around 12.5dBi corresponding to about 5°3-dB beamwidth.
