Optenni Lab design challenges

Optenni Lab features automatic matching circuit synthesis and optimization, antenna array beamforming with active impedance control, and many supplementary assessment tools. Optenni Lab is often used in conjunction with EM simulators, and several links are provided with major EM tools on the market.

The following are typical design challenges where Optenni Lab is used:


Optenni Lab synthesizes and optimizes broadband and multiband matching circuits which maximize the total efficiency of antenna systems. Optenni Lab takes into account several impedance environments, antenna radiation efficiency, component losses and tolerances. The effects of component layout can also be accurately modeled.

Optenni Lab optimizes the total efficiency of multiport antenna systems by simultaneous synthesis and optimization of the matching circuits at all antenna ports. The coupling and isolation between the antenna elements are taken into account as well as the dependence of radiation efficiency on the port termination. Our multiport capabilities support an arbitrary number of antenna ports.

Optenni Lab is widely applied in the optimization of tunable antennas, which typically are either frequency tunable antennas using aperture tuners or use closed loop tuners which adapt to various user environments. Optenni Lab supports switches, variable capacitor banks and more complex tuner chips as the tunable elements. Optenni Lab can calculate the exact radiation efficiency and radiation patterns of the antenna system as a function of the aperture components.

In this Optenni blog article, we take a look into some of the ways many Optenni Lab accelerates the design flow of antenna designs, and antenna matching in particular. We first focus on a straightforward one-port antenna, and then in later blog articles expand the story e.g. to the challenging domain of multiport (aperture tuned) antennas.

With the blog article of September 2023, we touched the main design philosophy of Optenni Lab, where the user may Explore the antenna, Accelerate the design of antenna matching, and Maximise the impact of matching. In this blog article, let me focus on the first aspect of this philosophy, Explore. Before matching circuits are synthesized and time is spent to gain adequate performance, it is very beneficial to get an overview of the theoretical limits of the antenna’s radiator. If the radiator has very little chance of surviving the communication task at hand, it is better to go back to the drawing board and try to redesign the radiator. After all, if a failure is to happen in engineering, it always pays off to fail fast and in early stages of the design, and then move on.

It is well known that compact wireless devices require small antennas whose size is dictated mostly by mechanical, design and aesthetic aspects, and not so much on the efficiency of radiation. Therefore, such small antennas are often made tunable to cater for multiband requirements. To make an antenna tunable, a switch is often incorporated to the antenna radiator. Such a device is also called an aperture-tuned antenna.

With this article I would like to welcome you to the new Optenni blog series. In this blog we will be discussing various matters related to RF circuit synthesis, impedance matching, antenna arrays and our Optenni Lab circuit synthesis software for antenna and RF optimization. When re-designing the pages, we also re-thought the key messages about our software. The key benefits of Optenni Lab can be condensed in the three verbs: explore, accelerate and maximize. Using these verbs, let me now explain in more detail what Optenni Lab can offer you. You may also have noticed a new look and feel for our web pages at www.optenni.com.
