The presence of antennas and antenna arrays in and around vehicles has become a commonplace with the introduction of wireless collision detection, collision avoidance, and lane departure warning systems. The two frequency bands considered for such systems are centered around 24 GHz and 77 GHz, respectively. In this example, we will investigate the microstrip patch antenna as a phased array radiator. The dielectric substrate is air. This example requires the Antenna Toolbox™. The figures show that both arrays have similar pattern behavior around the main beam in the elevation plane (azimuth = 0 deg). The patch-element array has a significant backlobe as compared to the cosine-element array. Conclusions This example starts the design of an antenna array for FMCW radar with an ideal cosine antenna and then uses a patch antenna to form the real array. The example compares the patterns from the two arrays to show the design tradeoff. From the comparison, it can be seen that using the isolated patch element is a useful first step in understanding the effect that a realistic antenna element would have on the array pattern.

Design of an 8X1 Square Microstrip Patch Antenna Array 73 uniform dielectric can support a single well defined mode of propagation at least over. Patch Antenna Designing - Free download as PDF File (.pdf). This chapter will covered the steps involved in designing the single patch and array antenna. ![]() Array Data StructureHowever, analysis of realistic arrays must also consider mutual coupling effect. Since this is a small array (8 elements in 2x4 configuration), the individual element patterns in the array environment could be distorted significantly. As a result it is not possible to replace the isolated element pattern with an embedded element pattern, as shown in the example. A full-wave analysis must be performed to understand the effect of mutual coupling on the overall array performance. Reference [1].
