Antenna Design

---

Antennas looked like very simple devices that every radio, television, mobile phone and automobile has. In fact they are not. They are very complex devices that convert electrical signals into radio waves which can be transmitted over the air or space. They are also able to grab radio waves right out of the air or space and convert them back into electrical signals in a receiver, thus giving birth to modern wireless communications, high speed broadband, and internet of things.

Antennas are often overlooked and taken for granted until it is too late. It is one of the key reasons for customer complaints and more often than not it is the cause of failure of wireless devices when it has been released into the market. Top performance antenna designs are very crucial to the success of a product in the market, and the design is a complex process requiring state of the art simulation tools, anechoic chambers and experienced RF and antenna specialists.

Antenna designs need to be done early in the design stage and embedded into the overall product design up front by taking into consideration its applications, frequency, bandwidth, form factors, mechanical constraints, and location of the antenna placement to reduce the overall product size, RF performance, cost and time to market.

In Cisspr, we use the following framework:

1. Concept and Definition

a.  Understanding the device applications and functionalities.

b.  Performance targets and design requirements.

c.  Mechanical and form factor requirements.

d.  Antenna placement.

2.  Antenna Design

a.  Design the antenna radiating elements using the 3D full wave electromagnetic simulation tools. 

b.  Design the antenna matching circuits using circuit simulation tools to optimise its performance.

3.  Prototyping & Validation

a.  Rapid prototyping of the antenna design after simulation.

b.  Validate and optimise antenna design performance and radiation pattern in advanced 3D full-anechoic chamber to meet the design requirements.

4.  RF Certification

a.  Pre-compliance and compliance measurements with accredited partner laboratories.

b.  Compliance report for global product certification.
