RF antennas play a critical role in the transmission and reception of wireless signals. The ability of a radio antenna to captures signals is dependent on its physical size, shape and efficiency. The TRA4703 from Taoglas is an omnidirectional antenna designed for medium range applications. This antenna is integrated with three inter-changeable connectors, SMA, FME and UFL. It offers 4.7dBi peak gain with a wide bandwidth of 890–960, 1710–2170 and 2500–2700 MHz.

The TRA4703 is suitable for a variety of applications that require good performance in both the TX and the RX direction, including GPS systems, GSM and CDMA telecommunication networks and WLAN networks. It is widely used in in-vehicle tracking and fleet management applications like road traffic control, security systems and disaster relief.

The TRA4703 antenna has a circularly polarised omnidirectional pattern. This means that the antennaradiates equally well in any direction, making it applicable in manycases. This antenna is engineered to have a low noise factor and great performance over a wide range of operating frequencies. The TRA4703 is weatherproof, providing improved performance under harsh environmental conditions.

The working principle of the TRA4703 is simple. A fixed wire conductor radiates a circular field pattern when excited with an electromagnetic source. This antenna is designed to be small yet offers good performance for applications requiring medium range. The gain of the TRA4703 is primarily a function of its size and the antenna is therefore more compact than other antennas of equivalent gain. The TRA4703 design uses a dielectric support projection that helps to ensure proper beamwidth performance. The broadband nature of the antenna also offers greater flexibility in supporting a wide range of frequencies.

In summary, the TRA4703 antenna is an omnidirectional, circularly polarised antenna suitable for medium range applications. Its 4.7dBi peak gain and wide operational bandwidth provide reliable signal transmission and reception over the 890–960, 1710–2170 and 2500–2700 MHz bands. The antenna is also weatherproof, making it suitable for outdoor applications. This antenna is designed to offer maximum performance and is an ideal choice for a variety of applications.
