Array antennas which are integrated onto lightweight structures of aircraft and Unmanned Aerial Vehicles (UAVs) are subject to unsteady aerodynamic loads. Mechanical forces and these aerodynamic loads will cause deformation of the antenna supporting structure. As a consequence, the positions and orientations of the elements of the array antenna change. The relative phases of the respective signals of the array antenna elements are affected, and therefore also the processing of the received signals is influenced. In this paper the effects of vibration of the array antenna on estimating Direction of Arrival (DOA) are investigated. To this end the MUSIC algorithm is applied to signals which are received by antenna elements of a demonstrator vibrating array antenna.

“…However there is also some disadvantages like lower efficiency and narrow bandwidth due to surface waves, feeding loss, dielectric loss. Hence to design antenna for prescribed shape without reducing performance is our new challenge [9][10][11][12][13]. Antenna array is known as conformal array when the elements of antenna are conformed on the surface like cylinder, sphere, a cone or other similar without causing extra drag.…”

This geometry can offer certain characteristics that can't be achieve by planner antenna. Antenna is design to function in 2.4 GHz wireless radio band. This work present performance of 4-element conformal antenna array for cylindrical surface and observe effect of mutual coupling between patch. In this, angle is preserved to conform the shape to reduce extra drag. The radius of cylinder is considered to be atleast one quarter wavelength or slightly more. The simulated results shows its resonant frequency is not affected with change in curvature however the radiation patterns are significantly affected more in elevation direction and less in azimuth. Simulations has been carried on CST software.

“…Some of these applications include antennas on vibrating surfaces such as aircrafts [3] and textile antennas [4]. Throughout much of this development, several different phase and amplitude compensation techniques [5] - [8] have been developed to autonomously recover the radiation pattern of a conformal antenna if the surface the antenna is attached to changes shape during operation.…”

The scanning characteristics of a linear five-element antenna array on a wedge-shaped conformal surface is investigated in this work. In particular, the half-power beamwidth (HPBW) of a self-adapting array is studied for various changing conformal surfaces. A general array factor expression is derived and used to compute the HPBW. From these results, the selfadapting limitations of the array are outlined. Finally, analytical computations are validated with measurements.
