Key Factors
Ground plane - During the design process, consideration
must be given to the size and configuration of the
ground plane. The ground plane has substantial effects
on the performance of the antenna. These effects include
frequency shift, gain, axial ratio and radiation pattern.
Element Size - The amount of space available for
the antenna element determines not only the material
required but also the related performance that can be
expected. The element size relates to the material that
will be selected, the shape of the element, and the
metallization pattern. Each of these has a substantial
effect on electrical performance.
Assembly Configuration - The final assembly
configuration also affects element performance.
The position of other components, etc. affects
the overall performance of the element.
The items mentioned above are areas in which
Spectrum Advanced Specialty Products engineering
staff can assist in developing an optimized antenna
element to fit your needs.
Patch Antenna Attributes
Small Footprint - Dimensions for antennas from
1 GHz to 3 GHz are from 13mm to 50mm square
(excluding the ground plane).
Low Profile - Antennas designed with higher dielectric
values are typically <8mm in height and depending
upon your bandwidth requirement can be as low as 4mm.
Lightweight - These small antennas can be worn on
people with little notice.
Versatile - Antennas not only transmit and receive circularly
polarized signals but also linearly polarized signals.
Low Cost - Our antenna elements are very affordable
in small and large volume.
Flexible - Antennas can be tuned and optimized very
easily making prototyping quick and cost effective.
Omni-directional - Antenna radiation patterns provide
excellent gain across all elevation angles but can also
be manipulated for more focused requirements.
Performance - These passive devices offer typical gain
response from 0 dBi to 3 dBi for half-power beamwidths
of 110 degrees. Gain at boresite (90 degrees elevation)
can exceed 6 dBi depending upon the proper selection
of a ground plane.
Military - We have extensive experience in building
hardened military designs.
Testing - All of our products are tested 100% on
custom testing systems to ensure quality performance.
