Radome

Patch antenna resonant frequency is significantly changed by the presence of any plastics and needs careful consideration in the design process. Selecting low-loss materials, ensuring proper thickness, and accounting for dielectric properties are key to minimizing negative effects. Proper radome design should strike a balance between protection and maintaining the antenna’s performance. The thickness of the radome affects how the waves are transmitted through it. If the radome is too thick, it can cause multiple reflections, leading to signal degradation. The shape of the radome (flat, spherical, etc.) can influence the antenna’s radiation pattern. For example, a curved radome might cause beam distortion or alter the antenna’s directivity.

Custom tuning The presence of plastics can cause significant shifts in the resonant frequency of a patch antenna, making tuning essential. The tuning process requires the customer to provide the enclosure, PCB, radios, other antennas, and a STEP file showing the antenna placement within the enclosure. Maxtena will then conduct tests and adjust the antenna to optimize its performance. After tuning, Maxtena will deliver a detailed report to the customer, including results on efficiency, gain, and radiation patterns.

Mounting When mounting embedded antenna to customer's product, it is crucial to avoid having metal screws or screw heads on the ceramic side of the antenna. Any metal components near the ceramic patch can significantly degrade performance.
