The demand for PCB Antennes in communication products is also growing.

Antennas are key components in many wireless systems, and printed circuit board (PCB) Antennes are widely used in the industry due to their small size and ease of integration with other high-frequency circuits.

The performance and consistency of a PCB Antenne is largely determined by the quality of its underlying circuit laminate, and its size is highly dependent on the target frequency and wavelength of the Antenne.

Ob es sich um persönliche Kommunikationssysteme (PCS), Anwendungen für das Internet der Dinge (IoT) oder elektronische Steuerungs- und Sicherheitssysteme für Kraftfahrzeuge handelt – es besteht kein Zweifel daran, dass die Nachfrage nach drahtlosen Anwendungen in diesen Systemen sehr groß ist.

With higher operating frequencies, from the 2.4GHz band for PCS applications to the millimeter wave (mmWave) frequencies for automotive advanced driver assistance systems (ADAS), Antennes are needed everywhere.

This is where PCB Antennes come into play - designers often turn to them as a practical solution to the growing number of wireless applications.

A high frequency PCB Antenne can be as simple as a microstrip patch fabricated on one side of a circuit laminate, with the addition of a slightly larger ground plane on the other side of the dielectric layer below it.

This low profile Antenne is ideal for installation in systems with any available flat surface.

Natürlich kann die Antenne radiation pattern of such a simple microstrip patch will be limited.

PCB Antennes using microstrip patches typically combine multiple patches on one PCB to achieve higher gain at a given operating frequency.

The size of the patch depends on the wavelength of the target operating frequency, usually half the wavelength, to achieve the best resonant Antenne characteristics at the target frequency.

Of course, RF/microwave PCB Antennes can be composed of many different transmission lines, such as stripline and coplanar waveguide transmission lines. They can even combine multiple different transmission lines in the same PCB Antenne .

Many suppliers offer PCB Antennes as manufactured components that can be added to system designs;

Some manufacturers also offer services to build PCB Antennes based on computer-aided engineering (CAE) design files or custom mechanical requirements.

For example, Advanced Circuitry International (ACI) can manufacture large Antennes (for lower frequencies) or large small Antennes on large circuit boards, such as 12× 18 inches and 18× 24 inches, using single-sided, double-sided and multi-layer PCBs Antenna configuration (Figure 1).

ACI manufactures Antennes on a variety of different substrate materials, including DuPont's high-performance flexible circuit materials and RF/microwave circuit laminates from leading circuit material suppliers such as Arron, Isola, Rogers and Taconics.

PCB Antennes are often supplied with adhesive to simplify installation in the intended application.

The selection of such circuit materials as the basis for a PCB Antenne is critical to its performance, especially when the PCB Antenne is used for higher mmWave frequencies and harsher operating environments (e.g., ADAS applications).

In some cases, PCB Antennes are provided as "components" with attached coaxial cables and Steckers for quick and easy interconnection to internal circuit boards.

One of the PCB Antenne suppliers, TE ConnecTIvity, has developed a wide range of PCB Antennes with cables and Steckers suitable for various frequency bands for personal communication system applications.

Insbesondere die PCB-Antennenbaugruppe Modell 2118060-1 von TE ConnecTIvity (Abbildung 2).

Es kann eine Betriebsfrequenz von ca. 2.4 bis 2.5 GHz bereitstellen Bluetooth, Wi-Fi und Wireless Local Area Network (WLAN).

Cable length is 13.78 inches (350 mm), with a choice of different types of Steckers such as MCIS and MHF Steckers; PCB Antenne includes adhesive for mounting on flat surfaces.

Likewise, Taoglas Antenna Solutions' FXP07.07.0100A is a low-profile flexible PCB Antenne with short cable lengths and IPEX Steckers und Klebeband zur einfachen Klebemontage auf ebenen Flächen (Abbildung 3).

Compliant with RoHS compliant Antenne designs for "five-band" frequency bands including AMPS from 824 to 896 MHz, GSM from 880 to 960 MHz, DCS from 1710 to 1880 MHz, PCS from 1850 to 1990 MHz, and UMTS from 1710 to 2170 MHz.

The compact 50Ω Antenne measures 41×24 mm with linear polarization and an omnidirectional radiation pattern.

A growing trend in PCB Antenne design is multi-band coverage to accommodate systems with broadband frequency ranges or multiple applications.

For example, Pulse Electronics' CW3315B0100 series of flexible PCB Antennes are dual-band Wi-Fi Antennes designed to cover the 2.4 to 2.5 GHz and 4.90 to 5.85 GHz WLAN frequency bands (Figure 4).

This is also a PCB Antenne assembly with a 100mm cable and standard IPEX Stecker für eine einfache Anbindung an die Anwendung.

Die Miniatur Antenne assembly provides greater than 50% Antenne efficiency and is designed for internal installation in Wi-Fi products.

Die Dualband-/Breitbandabdeckung des CW3315B0100 ist ein repräsentatives Beispiel für industrielle Anwendungen und praktische Anwendungen von IoT-Geräten und Ausrüstung für die öffentliche Sicherheit.

While it is very easy to mount such a tiny PCB Antenne with adhesive, it can sometimes result in the absence of any type of ground plane, which reduces Antenne Effizienz.

While the underside of a PCB Antenne laminate is usually the ground plane, the larger ground plane required for higher efficiency may increase the physical size of the PCB Antenne, which must be considered when the Antenne is mounted in the application.
