“…In contrast to other formulations that consider the array composed of isotropic elements, the formulation presented in this paper takes into account the real embedded radiation patterns of the array elements. The negative impact of considering isotropic antennas for the synthesis instead of real-microstrip elements has been demonstrated in [11].…”

This study presents a technique to design antenna arrays with shaped radiation pattern. The efficiency of the proposed technique is demonstrated for the optimisation of a linear microstrip array for radio base stations of mobile communication systems. The main beam is shaped so as to provide uniform distribution of power inside a sector of a cell and to minimise the power radiated above the horizon. The synthesis of the shaped pattern is achieved by a combination of genetic algorithm and sequential quadratic programming. In contrast to several papers found in the literature that consider only isotropic antennas, the proposed approach takes into account all the radiation properties of small arrays, such as the mutual coupling between the array elements and edge effects. Finally, the design of the feeding system to produce the synthesised pattern is discussed. Measurements are used to validate the proposed technique.

“…Microstrip technology is used in several applications, such as global positioning system (GPS) [2], mobile communication systems [3] and among others. In many of these applications, beam steering capability is desired, whereby the control of radiation pattern parameters such as half-power beamwidth and sidelobe level is necessary in order to reduce radiated power into unwanted directions.…”
