Additionally, the First Null Beam Width (FNBW) is targeted for optimization without predefined values. The optimization approach also considers the effect of thinned array element spacing on the overall performance metrics. Out of total 36 elements, only 15 elements are switched ON and the remaining...
We describe the general procedure in order to maximize the capacity for our considered geometry, which consists of a circular arc array at the transmitter and a uniform linear array (ULA) at the receiver. The method is based on the optimization of the interelement distances at the transmitter ...
The conformal FSS is 3D printed and copper electroplated, which leads to a low-cost and lightweight bandpass filter array. Placing it in the near-field region of a primary antenna can be used as radomes to realize compact high-performance mm-wave systems. The comparison between simulated and...
The number of beams in the FOV is given by , with main beam point direction (all angles are expressed with respect to the normal of the antenna aperture), where is the angular range of azimuth scanning. Assume the radar system utilises an N-element uniformly spaced linear array with inter...

The suggested design makes use of the concept of a metasurface by including a Frequency Selective Surface (FSS) underneath the radiating element. This research paper aims to present the design and performance analysis of FSS embedded antennas with a special focus on the terahertz frequency band. Th...
Deep neural networks have shown great performance for direction-of-arrival (DOA) estimation problem, but it is necessary to design some suitable networks to solve the multi-DOA estimation problem. In this paper, we use Khatri–Rao product to increase the
12. The ball grid array package as defined in claim 10, wherein the at least one conductive element interconnects all of the leads that define the perimeter of the matrix. 13. The ball grid array package as defined in claim 10, wherein the perimeter is defined by all of the leads of ...
The directional rotating antenna includes a two-by-two array of antenna elements where each element is an end driven half-wavelength resonating antenna element supported by a length of conductor perpendicular to the wall of the microwave oven cavity. A parallel plate transmission line connects to ...
it should be noted that the upper side band could alternatively be removed from the RF signal. The RF signal (which now contains only the upper side band) is then amplified by an RF power amplifier58and passed through a circulator60to the antenna62. In this technique the key element is ...
