The use of parasitic wire dipoles are examined when placed in the proximity of a focused dipole feed in a parabolic reflector antenna. These parasitic elements are rotated around the feed dipole and a search is performed for the ideal positioning so as to yield maximum radiated power and main beam shift in order to develop a novel form of angle diversity. In addition a comparison is made between 2 element dipole feed structures and linearly and circularly polarised patch feed structures. In order to analytically model the structure, mutual coupling between feed elements is calculated taking into account a varying reflection coe±cient due to an impedance mismatch between the transmission line and driven element. An analytical treatment of the calculation of the radiated co-polar and cross-polar feed pattern is presented in addition to the projected field at the reflector surface. A comparison is made to the results presented by E.M.T Jones in the 1954 IRE Transactions of Antennas and Propagation paper entitled 'Paraboloid Reflector and Hyperboloid Lens Antennas'. A theoretical treatment of the reflected field and far field radiation pattern is then presented using the methods of Geometrical Optics, Physical Optics and Fourier analysis. The author derives analytical equations for multiple element incident feed fields and surface current equations for half wave feeds of arbitrary position and number. The fndings are confirmed using a comparison of three methods. These are; original code developed from analytical derivations, the NEC2 Method of Moments using a meshed reflector model and finally, by experimental methods. Analysis of a 30cm 0.4 F/D prime focus reflector at 3GHz using a 2 element feed yields up to 2dB gain over a single dipole feed when the element is displaced either laterally or at 60 or 120 degrees from the feed axis. The optimum offset from the driven element is in the 0.4 to 0.6¸ range. Maximum beam shift for this structure at the half power points is shown to be approximately 10 degrees. When designed as a low-cost system with undemanding polarisation requirements the structure presented provides an easily implemented or retrofitted alternative to multiple antenna diversity solutions.
