Analysis of the mutual coupling in finite arrays of printed quadrifilar helical antennas

The design of arrays needs an accurate estimation of the mutual coupling between the elements of the array. Here, we analyze small arrays of printed quadrifilar helical antennas (PQHAs), taking into account the mutual coupling effect on the array element input impedance and radiation pattern. Experi...

Description
Summary:The design of arrays needs an accurate estimation of the mutual coupling between the elements of the array. Here, we analyze small arrays of printed quadrifilar helical antennas (PQHAs), taking into account the mutual coupling effect on the array element input impedance and radiation pattern. Experimental results of input impedance and mutual coupling are also given. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 34–40, 2001.
