GPS antenna application introduction


The role of the GPS antenna is to convert the electromagnetic energy of the radio signal from the satellite into the current that can be taken by the receiver electronics. The size and shape of the antenna is important because these features determine the ability of the antenna to obtain a weak GPS application signal. The antenna can be designed to operate at a single L1 frequency, or at both L1 and L2 frequencies, as needed. Since the GPS signal is a circularly polarized wave, all of the receiving antennas are in the form of polarized work. Despite the variety of conditions, there are still many different types of antennas that exist, such as unipolar, bipolar, spiral, four-armed, and microstrip antennas.

Microstrip antennas are the most common type of antenna due to their durability and ease of manufacture. Its shape can be round or square or rectangular, like a copper printed circuit board. It consists of one or more metal pieces, so the most commonly used shape of the GPS antenna is a massive knot, like a biscuit. Since the antenna can be made very small, it is suitable for aerospace applications and personal hand-held.

Another major characteristic of the antenna is its gain pattern, ie, the directionality. Using the antenna's directivity can improve its anti-dry and anti-multipath effects. In the precise positioning, the stability of the phase center of the antenna is a very important indicator. However, in ordinary navigation applications, people want to use omni-directional antenna, at least to receive antenna horizon above the five-dimensional view of all the sky in the visible satellite signal. Microstrip antennas usually have a ground plate as a ground network. As the GPS signal to reach the receiver is generally relatively weak, so often use active antenna, the so-called active antenna, refers to the antenna with RF preamplifier or low noise amplifier.
