Tuneable Radar Antenna Array Design for Air-to-Air Communication

Abstract

In last few decades Unmanned Aerial Vehicle (UAV) served the society for different purpose such as surveillance, product delivery, path planning, agriculture, etc. Due to its extensive endurance and agility in detecting targets, unmanned aerial vehicles (UAVs) play a significant role in surveillance. Sensors, which could be put on the UAV, are required to access data in the observation area. Radar, especially those used for monitoring and defence reasons, may execute a range of jobs, change arrangement parameters, and alter performance levels in response to the particular characteristics of the environment in order to offer the optimum response and handling. Communication is critical for data transfer and reception in any application. This study focuses on air-to-air communication utilising $4 \times4$ tuneable radar antenna array. CST software is used to build and analyse the performance of tuneable antenna arrays for a variety of arrangement such as Uniform Linear Array (ULA), Uniform Rectangular Array (URA), and Uniform Circular Array (UCA), based on directivity, gain, and radiation efficiency.
