Multiple input multiple output antenna is the key technology which enables the design of 5 G networks. In order to achieve desired beam forming and side lobe reduction capabilities, antennas used in MIMO technology are required to feed with signals having different phase and amplitude. It is possible to achieve variable phase shift and variable attenuation using phase shifter and amplitude limiters. However when these devices are used between source and antenna, they makes the system non planner and non-conformal. This research presents a 16 element, multiple user MIMO Patch antenna with conformal and planner power divider network to achieve electronically steered beam along with desired side lobe level reduction. Wilkinson power divider is used to achieve conformal and planner power divider for MIMO antenna. Desired beam forming capabilities are achieved by controlling the phase of input signal to antennas by controlling the length of microstripline and desired side lobe reduction capabilities are achieved by controlling the amplitude of input signal to antenna by controlling the width of microstrip line used in Wilkinson power divider. This provides an overall planner and conformal structure. In this research same antenna is used is generate two major beams by controlling the phase and amplitude of input signal. The achieved radiation pattern of designed antenna consists of one major beams having gain of 18 dB and located at theta equal to 100 and Phi equal to 1800. When phase of input signal to antennas are changed a major beam having gain of 18 dB and located at theta equal to 100 and Phi equal to 2700 is obtained. The side lobe level less than 13 dB of main beam is achieved using designed antenna. The designed structure is simulated and analyzed using HFSS. Simulated results for the designed MIMO antenna are verified by analyzing the fabricating structure using vector network analyzer and horn antenna.

“…However, it is possible to generate a certain size approximation for the non-diffractive beam which propagates over a finite distance [2]. Due to the non-diffractive characteristics, the beam is widely used in microwave nondestructive detection [3,4], wireless power transmission [5,6] and covert communication [7][8][9][10] etc.…”

A transmission phase-shifted metasurface (PSM) array has been proposed for nondiffractive beam deflection. A PSM element consists of two identical semicircular rings and an I-shaped structure, which is symmetrically printed on both sides of the F4B substrate. According to the geometric optics, the phase distribution on the metasurface can be obtained. To achieve the desired phase distribution, the metasurface elements rotated at different angles are rearranged, since the phase of the transmitted wave is manipulated by rotating the metasurface element. Then, the standard horn is used to produce the sphere wave across the proposed metasurface array for the non-diffractive beam deflection. Simulated (measured) results show that the inclined non-diffractive beam can be generated at a tilted angle of 35°(34.9°) with a maximum non-diffractive distance of 100 mm (97.5 mm) at 10 GHz. The proposed metasurface array has the advantages of nondiffractive beam deflection, low sidelobes and miniaturisation.
