“…The gain of the antenna can be further improved by considering an array topology [2,14]. The main drawbacks of the array are their large size and complex feed network [15][16][17][18][19][20][21][22][23][24][25][26][27]. In an array network, power divider is essential to distribute the power with equal amplitude and phase to each element of the array.…”

In this paper, a low-profile fractal antenna and its array for DSRC-band applications have been proposed. The proposed single element is a newly designed fractal antenna which is right-handed circularly polarized (RHCP) and derived from the Koch-snowflake 1st-iteration. Moreover, a diagonal slot defect in the ground plane has been implemented for resonating the structure at the desired frequency and, to get a low cross-polarization over the operating frequency. The compact feed-network of the array is designed using a Wilkinson power-divider. A single element and a 4 × 1 antenna array are designed, prototyped, and verified. The antenna array is designed by a single-layer microstrip structure with a compact size of 151.70 × 43.50 mm 2 . According to the experimental results, the single element and the antenna array have S 11 of −15.27 dB and −13.95 dB, and RHCP gain of 6.14 dBic and 11.98 dBic, respectively. Moreover, the computed radiation efficiencies of single element and array are 78.17% and 71.50%, respectively, while CP bandwidths of single element and array are 49.00 MHz and 58.00 MHz, respectively. The performance of the proposed RHCP antenna is suitable for the DSRC-band application.

The paper deals with the optimization of the sparse planar antenna array for direction of arrival (DOA) estimation in two dimensions (azimuth and elevation). The optimization algorithm was proposed on the basis of the peak sidelobe level (SLL) and half-power beamwidth (HPBW) parameters. In empirical validation, we have set up a measurement system to test the efficiency of an optimized array configuration. The array was configured using the patch antennas with frequency band 2.4 GHz. In comparison with several popular array configurations, the experimental results show that the proposed antenna array was optimized, and it provided higher accuracy and resolution in two-dimensional (2D) DOA estimation.
