The founders of Taoglas have a very strong background in Electroceramics. This material is extremely suitable for antennas because of its stability, resistance to detuning (including effects of the body) and its dielectric properties. We have the expertise to achieve high dielectric constants from the ceramic mix. As antenna size decreases, Q increases so ceramics allow Taoglas to design miniature ceramic antennas WITHOUT performance compromise at a competitive price.
The advantage Taoglas have is control over the material used. We have direct input and control over the ceramic powder formula (raw material) itself before it goes through the antenna manufacturing process. This means quality can be tightly controlled leading to the same result each time. It eliminates differences in material properties (and therefore performance) between antenna production batches.
We have designed the smallest antennas in the market, for example the AP10 and AP12 GPS active patch modules. Our small SMT GPS patches for automotive use are truly unique. Ceramic patches deliver the best performance for GPS and this is undisputed in the industry.
The ceramic used also prevents cracking at high temperature and environmental tests. An example with Cellular is our SMT mounted PIFA range of antennas PA.22A Tri-Band, PA.25A Hexa-Band, PA.700A Wide-Band.
FR4 material delivers simplicity in implementation and installation. PCB is a very useful material where space is not as critical as mobile phone or consumer devices. Tuning, customisation, tooling and production can be done quickly and cheaply. They are ideal for GSM, WLAN, WiFI and WiMax applications where a cable and connector is required for module connection. A variety of cables and connectors are available for each model. Various mounting options can be implemented as it is very easy to add holes for screws or double sided tape or foam to secure the antennas.
Flexible PCB Antennas
Taoglas have recently implemented many unique (patents pending) custom antenna designs using flex circuit material. The drive from the wireless industry to miniaturize antennas has led us to develop these solutions. They have a very low profile (thickness comparable to a sheet of printing paper) and can be affixed to the housing of the device, on the main PCB board or to a plastic holder to separate it from crowded PCB’s. The tooling costs are minimal and a custom solution can be implemented quickly. The antenna can be folded onto the circuit essentially making the antenna “big” on a small surface area that has minimal impact on device space requirements. The material allows high efficiency so like metal antennas they are suitable to devices which require optimum performance or PTCRB approvals.
Folded bent metal antennas deliver high efficiency and are suitable to small devices where space is limited. As tooling is required for the metal shape, and also the possibility of more tooling for plastic carriers these solutions are only suitable for higher volume applications (mobile phones, tracking devices, M2M). As high efficiency can be achieved they are often used in cases that require PTCRB approvals.
Folded bent metal antennas deliver high efficiency and are suitable to small devices where space is limited as the designer can bend the metal shape to suit the device topology. As tooling is required for the metal shape (and also the possibility of more tooling for plastic support carriers) these solutions are only suitable for higher volume applications (mobile phones, tracking devices, M2M) or applications that can justify high NRE costs. As high efficiency can be achieved they are often used in cases that require PTCRB approvals as dipole, monopole or PIFA types can be constructed. They are less affected by the effects of metal on the main PCB or in the device housing than other antennas. This is because they are designed to be removed from the ground-plane.
A fibreglass antenna can simply be described to a multi-layer PCB antenna where the antenna trace can be folded up along layer by layer. For that reason they are useful for multi-band antenna requirements (4-5 bands +), so cellular or Wi-Max device applications. SMT mounting is possible and an example is our PA-23 dielectric monopole antenna.
