RF Antennas play an important role in various applications, such as wireless communication, wireless data transmission, military applications, broadcasting, and more. The B4705CR is one such antenna made by Taoglas, a company that manufactures various types of antennas for mobile and embedded applications. The B4705CR is a quad-band antenna that covers four frequency ranges: 698-960 MHz, 1710-2170 MHz, 2400-2500 MHz, and 5150-5850 MHz. This antenna is designed to optimize performance and offers reliable performance over a wide frequency range.

The B4705CR has a dual-polarized feed structure, meaning it can transmit or receive in both vertical and horizontal orientations. This antenna element features a printed PCB antenna design, and its low profile makes it an ideal choice for portable radio applications. The B4705CR has an IPEX connector interface that makes it easy to integrate into a product’s design. Moreover, this antenna is tested to ensure a wide Operating Temperature Range (-40°C to 85°C).

The B4705CR antenna provides a gain of up to 5 dBi, which makes it an ideal solution for applications that require a high-sensitivity link because of its low cost. The antenna also has a low VSWR (Voltage Standing Wave Ratio) of 1.5:1Max, meaning that it does not suffer too much from reflected energy, and thus delivers high signal integrity. Furthermore, the B4705CR has a VSWR stability of 0.8:1, meaning it will not vary too much when antenna depth and orientation are changed.

The working principle behind the B4705CR antenna is based on a dual linear polarized design. It consists of two antenna elements on a single printed circuit board. Each antenna element is split into two halves, which are then connected to the feed structure in two different orientations. The result is a dual-polarized antenna with both vertical and horizontal orientations. This antenna is typically used in applications that require a high-sensitivity link and wide frequency coverage.

The B4705CR antenna is designed for various applications, from mobile phones and handheld radios to Wireless Local Area Networks (WLANs) and Bluetooth. It is also an ideal solution for Internet of Things (IoT) applications, such as for monitoring weather conditions or environmental changes. In addition, this antenna is also used in various embedded wireless modules that require services such as GSM, GPRS, EDGE and UMTS for applications such as safety features and tracking.

Overall, the B4705CR antenna is an ideal solution for applications that require a reliable signal, high-sensitivity link, and wide frequency coverage. It features a low profile design, low VSWR value, and VSWR stability, making it suitable for various mobile and embedded applications.
