Image of the Dipole panel array
The dipole panel array includes a grid reflector, along with four dipoles and their respective quarter-wave baluns, which enable feeding of the structure using an unbalanced coaxial line. This practical and simple antenna is suited to low-cost and robust applications.
The equal amplitude, progressive phase excitation of the four-element array produces a circularly polarised pattern. The omnidirectional radiation pattern of the dipole element is transformed into a single broadside lobe through the addition of the reflector.

Various methods have been suggested to overcome the limitation bandwidth of microstip antennas, including the use of gap- or direct-coupled parasitic patches. In the FEGCOMA, these parasitic patches are placed alongside all four edges of the driven patch...
The Corrugated pyramidal horn is a variation of the standard Pyramidal horn. The addition of corrugations to the standard pyramidal horn improves the back and sidelobe level performance. Higher back- and sidelobe levels result from energy diffracted by...
The standard rectangular patch forms the basis for a number of antenna variations, typically introduced to overcome a particular shortcoming of the standard structure. One approach to reduce the size of a patch antenna involves removing a rectangular...
The horn antenna designed here makes use of quad ridges with two orthogonal feeds to achieve this dual polarization. The feeding structure has the advantage of being able to support a fundamental propagation mode polarized in either of two orthogonal...
The antenna consists of an axisymmetric parabolic reflector and a metallic cylindrical shroud which extends from the rim of the reflector dish. The physical feed antenna is substituted by a theoretical / simulated / measured pattern, simplifying the overall...
