Colocated Magnetic Loop, Electric Dipole Array Antenna (Preliminary Results)

摘要

We present a detailed electromagnetic analysis of an electrically small colocatedelectric dipole and magnetic loop antenna array. This antenna is the simplest example of the Grimes multipole class of antenna arrays. We have determined that since the interaction term between the two elements disappears from the radial complex power, we were able to set the radial reactance to zero by choosing appropriate current magnitudes and phases on the array elements. By driving the two elements in quadrature, we obtained a much increased radiation intensity and directivity as well as increased radiated power.
