SPE-21-8-119-E 

The Taoglas Universe PCS.50.A is a patent pending active Cellular and GNSS antenna designed specifically for IoT devices with small ground planes. With an unprecedented level of integration, it combines aperture tuning and active switching technologies to provide wideband coverage for GNSS and cellular connectivity. 

The PCS.50.A has an RF switch to adjust the resonance frequency of the antenna depending on the device’s requirements. The aperture tuning technology allows the antenna to cover the whole spectrum of 4G LTE/5G bands by adjusting the resonant frequency of the antenna to the desired frequency band of operation. This allows the device to use the correct frequency band required by the radio module. Additionally, a second active switch can be simply added if either Cellular or GNSS needs to be selected. 

The PCS.50.A is compatible with the radio modules that support the RF front-end control interface (RFFE). The radio module controls the active RF switch to adjust the antenna resonance frequency to operate efficiently on multiple bands and increase the RF capabilities by 3dB compared with standard passive solutions. This will in turn, improve the Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS). 

The PCS.50.A is easy to integrate using standard SMD technologies, and implementing the active solution is easy thanks to Taoglas’ integration support, providing different design files depending on your requirements. The antenna can be tuned by simply selecting the best switching configuration to achieve the optimum antenna performance. 

Taoglas has developed an evaluation board PCSD.50.A to demonstrate the antenna performance for 4G/LTE applications. The PCSD.50.A is just 40 x 50mm, makes it suitable for even the smallest of IoT and CAT-M devices. Typical applications include IoT devices such as smart sensors requiring cellular and GNSS connectivity, wearables or asset tracking. The antenna itself measures just 38 x 10 x 1.6mm, and as it is manufactured from high-grade FR4 PCB, it is lightweight; yet robust, and it is supplied on tape and reel.

Taoglas has developed another evaluation board PCSD.50.B to demonstrate the antenna performance for 5G connectivity. The PCSD.50.B evaluation board is just 40*70mm, it covers the most challenging bands for 600MHz, making it suitable for 5G applications. 

The datasheet consists of two parts mainly. The first part focuses on the 4G/LTE antenna integration and performance on the PCSD.50A evaluation board. The second part focuses on the 5G Antenna integration guidance and performance on the PCSD.50B evaluation board.

SPE-21-8-119-E 

Taoglas developed an evaluation board called PCSD.50.A that includes the PCS.50.A antenna, RF switches and other components to operate this smart antenna solution. This is available to order from Taoglas. Taoglas developed this EVB to help customers in implementing this solution on their applications. The evaluation kit uses a simple RF switch SP4T to select different matching circuits and a SPDT to select GNSS or LTE radios. 

The RF switches used in the evaluation kit are: 

- SP4T: Infineon BGSA14GN10 

- SPDT: Infineon BGS12SN6E6327XTSA1 

In the evaluation kit, both RF switches are controlled by the DIP switch, representing the control interface of the radio module. The DIP switch is connected to a 3V coin battery (CR02032). 

The DIP switch has two states: 1 represents ON, 0 represents OFF. 

The DIP switch is a 10 way switch, numbered 1 to 10. 

Pins 1-3 are used to control the SP4T (U2): 

Pin 1 controls the power to SP4T, Pin 2 connects to the CTRL 1 on the RF switch, Pin 3 connects to the CTRL 2 on the RF switch.

Pins 9-10 are used to control the SPDT (U1): 

Pin 9 is the control input for the SPDT, 0 = GNSS, 1 = LTE, Pin 10 controls the power to SPDT.

The matching components M1-M4 are connected to the SP4T switch. These are used to tune the antenna resonances.  The values for these components are shown in the mapping table below.

|---|---|---|---|---|
|0|0|S1:M1-ANT|5.6nH,<br>MLK1005S5N6ST000|698-746MHz<br>&1710-2690MHz|

An additional matching circuit at the antenna feed side may be necessary for some applications to provide additional tuning options. Taoglas recommend incorporating extra component footprints, to form an ‘’L’’ or “Pi” matching network between the antenna feed and the radio module. On the PCSD.50.A evaluation board, an L network is reserved but it is not used as there is a zero Ω link fitted in this case.
