“…When target is not maneuvering, the process noise is less. When target maneuvers, the process noise increases [10,11]. So, in simulation, the covariance matrix is multiplied by fledge factor of 10 for the time period of target maneuver.…”

In this paper effort is made to track a maneuvering target using Unmanned Aerial Vehicles (UAV) with range, bearing and elevation measurements. Extended Kalman filter is preferred to processmeasurements tampered with noise. Algorithm to detect the maneuver of target is developed in this paper. This information about range, bearing and elevation is communicated to weapon guidance station by means of personal communication system between UAV and weapon guidance station. Mathematical modeling in detail and simulation results is presented.

“…The patch antenna structure is responsible for achieving parameters. A circular patch antenna helps to get a wider bandwidth compared to other structures [4]. In response to these challenges, several approaches have been recommended, including substrate electrical thickening, incorporating slots on the patch, and employing defected ground structures (DGS) [5].…”

This paper presents an innovative high-gain multiple-input-multiple-output (MIMO) antenna featuring a compact circular shape, enhanced by strategically positioned slots, slits, and defected grounds created by etching multiple iterations of a circle inserted with a triangle shape. The investigation thoroughly explores the various traits and properties exhibited by the antenna. The antenna design harmoniously incorporates two radiating elements shaped in circles, positioned 16 mm apart from their centers, and has been physically constructed using an FR4 substrate. Enhancing the antenna's bandwidth and gain requires the implementation of slots with fractal patterns on the ground with a precise edge-to-edge separation of 2.5 mm. The placement of the antenna elements at a 16 mm distance guarantees an isolation level exceeding 15 dB consistently throughout the entire wideband frequency range. The dimensions of the compact MIMO antenna are tailored to be 1.12λ × 1.8λ × 0.091λ (20 × 32 × 1.62 mm 3 ). In this study, the circular patch MIMO antenna with a fractal defected ground structure (DGS) resonates precisely at 16.903 GHz. It showcases an impressive impedance bandwidth spanning 2.027 GHz, ranging from 15.946 GHz to 17.973 GHz. It exhibits a reflection coefficient of −43.82 dB and achieves an observed gain of 6.25 dBi. The observed results include a minimal envelope correlation coefficient (< 0.025) and a substantial diversity gain (> 9.89).The measured results mirror the simulated outcomes, affirming the effectiveness of the wideband, high-gain antenna design. Its bandwidth and gain are well-suited for satellite communications, particularly in downlink applications, enabling faster data transmission rates.

“…1 The multiband feature for microstrip patch antenna can be achieved by introducing different slots, stubs and by different feeding techniques. 2,3 This technique results to miniaturizing the antenna size and enhancing the antenna performance at desirable frequency bands. From the literature, E-shaped patch antenna, [4][5][6][7] with different slotting techniques was designed for wireless communication application.…”

A monopole rectangular shape patch antenna (RSPA) with trapezoidal shape complementary split ring resonator (CSRR) is designed for wireless communication application is presented in this paper. The trapezoidal shape CSRR is considered to obtain circular polarization and rectangular slit is considered to operate antenna for triple frequencies at 1.88, 4.17, and 6.73 GHz, respectively. The axial ratio of 1.25, 1.05, 1.28 dB is observed and a maximum gain of 6.29 dBi at 1.88 GHz frequency is produced. The RSPA model is designed for mobile and fixed satellite application.
