where D is the diameter of the antenna ( (N-1) × d for our uniform linear array) For a small array (small D) or a low frequency (large λ), the far field distance is small. But for a large array (or ...

The multiple, fixed TR/RX antenna arrays in this radar were optimized for range, angle, and side-lobe suppression. A patch antenna is relatively easy to design and manufacture and will perform quite ...

A reconfigurable antenna array integrated with RF switches Date: November 10, 2013 Source: Universiti Teknologi MARA (UiTM) Summary: The recent rapid development of wireless communication systems ...

Our signal’s carrier frequency is 100 MHz, and the receiver is a uniform linear array (ULA) with 10 elements spaced by half wavelength. The signal source is 45 degrees of the array boresight.

Introduction In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a ...
