In the drive for the development of wideband array antennas for military applications, a well designed balun is essential to achieve overall antenna performance. However, for balanced antenna arrays to be driven effectively, antiphase element feeds are required at the correct impedance over multiple octaves. This paper summarises balun design options in microstrip and stripline for use with highly...
Presently most wide band array elements are complicated 3-dimensional structures which are difficult and costly to manufacture. Therefore we explore planar patch elements which offer a simplified geometry with potentially reduced weight and cost and are suitable for conformal applications. We use a genetic algorithm to design a patch element in a unit cell of an infinite periodic array and model the...
The paper presents general properties of arrays of connected slot or dipole antennas providing guidelines for the design of structures. Connected arrays represent one of the most promising array antenna concepts able to meet the very demanding requirements in terms of antenna bandwidth and high polarization purity, imposed by the new generations of radar systems. This array concept can also be applied...
