TL;DR: In this paper, the mutual impedance between the dipole elements of the antenna is taken into account, and the field radiated due to a surface wave reflector of finite extent is determined by calculating the surface current distribution on the reflector plate.
Abstract: A method is set up for a theoretical investigation of arbitrary backfire antennas based upon dipole structures. The mutual impedance between the dipole elements of the antenna is taken into account, and the field radiated due to a surface wave reflector of finite extent is determined by calculating the surface current distribution on the reflector plate. Numerical results obtained for Yagi backfire antennas and short-backfire antennas using this theory are compared with experimental results.

TL;DR: It is shown that for waveguide arrays systematic procedures for manipulating a minimum number of parameters can be arrived at that lead to optimum performance reliably and efficiently.
Abstract: Phased-array antennas operating in a linear or unidimensional scan mode are currently rising rapidly in importance with the emergence of a number of radar systems which employ advanced signal processing techniques but which do not require a full, and more expensive to implement, two-dimensional scanning capability. This simplification of the scanning feature permits the derivation of far more extensive array aperture design guidelines than is possible for a two-dimensional scan. It is shown that for waveguide arrays systematic procedures for manipulating a minimum number of parameters can be arrived at that lead to optimum performance reliably and efficiently. The approach ranges from the general, involving overall system aspects, to the specific, presenting a tableau of comprehensive practical design information not available elsewhere. In addition, various related subjects central to phased-array performance are discussed with particular attention on the increasingly important topic of wide frequency agility. A description of the antenna system of the multiple antenna surveillance radar (MASR) and its unique and unprecedented performance features is also included.

TL;DR: The design and development of two novel dual-band coplanar waveguide (CPW)-fed slot antennas for broadband wireless applications is presented, aimed to cover the gap in the multiband wireless applications domain.
Abstract: The design and development of two novel dual-band coplanar waveguide (CPW)-fed slot antennas for broadband wireless applications is presented. The first antenna operates in GSM (1.7-1.9 GHz) and IEEE 802.11b (2.4-2.5 GHz WLAN) frequency bands, while the second antenna operates in the 802.11b (2.4-2.5 GHz) and 802.11b (5.1-5.9 GHz) frequency bands. These antennas are aimed to cover the gap in the multiband wireless applications domain. Simulation work has been performed using commercially available three-dimensional electromagnetic tools and prototypes have been built in order to explore the actual performance of these two antennas. Satisfactory agreement in simulation and experimental results is shown. These antennas can easily be attached on the backplane of PDAs, smartphones or notebooks, to meet users' needs for wireless connectivity in a small form factor.

TL;DR: In this article, a compact MIMO terminal antenna employing Yagi-Uda arrays with common director elements is proposed, which provides a high gain in the horizontal direction even when the array is arranged horizontally.
Abstract: In this paper, a compact MIMO terminal antenna employing Yagi-Uda arrays with common director elements is proposed. The Yagi-Uda array provides a high gain in the horizontal direction even when the array is arranged horizontally. The size of the proposed antenna is fairly small because the director elements are shared between two Yagi-Uda arrays that face each other and the length of the array is approximately half of two individual Yagi-Uda arrays.

TL;DR: In this article, an apparatus and a method for mapping virtual antennas and physical antennas in a wireless communication system is presented. But the method does not address the problem of wireless communication in many-to-many relation.
Abstract: An apparatus and a method for mapping virtual antennas and physical antennas in a wireless communication system. The method for mapping the virtual antennas and the physical antennas includes generating at least two virtual antenna signals for at least two virtual antennas. The method also includes generating at least two physical antenna signals by applying a corresponding matrix, which maps the at least two virtual antennas and the at least two physical antennas in many-to-many relation, to the at least two virtual antenna signals. The method further includes transmitting the at least two physical antenna signals over respective physical antennas.
