MikroTik 60 GHz access point with 3 antenna arrays. MikroTik develops a variety of wireless antennas designed for different use-cases. These include sector antennas, dish antennas, and omni antennas, each offering unique coverage patterns and distance capabilities for outdoor wireless connectivity.
Multiple patch antennas on the same substrate (see image) called microstrip antennas, can be used to make high gain array antennas, and phased arrays in which the beam can be electronically steered. A variant of the patch antenna commonly used in mobile phones is the shorted patch antenna, or planar inverted-F antenna (PIFA). In this antenna ...
Most wireless embedded networks use omni-directional antennas and therefore neighbors can overhear communication in and out of nodes. This was used this to develop a primitive called " local monitoring " [ 51 ] which was used for detection of sophisticated attacks, like blackhole or wormhole, which degrade the throughput of large networks to ...
Antenna reactance may be removed using lumped elements, such as capacitors or inductors in the main path of current traversing the antenna, often near the feedpoint, or by incorporating capacitive or inductive structures into the conducting body of the antenna to cancel the feedpoint reactance – such as open-ended "spoke" radial wires, or ...
According to the Telcordia industry standard that establishes generic requirements for Fiber to the Antenna (FTTA) protection GR-3177, [5] the RRH shifts the entire high-frequency and power electronic segments from the base station to a location adjacent to the antenna. The RRH will be served by optical fiber and DC power for the optical-to ...
A quad antenna is a self-resonant loop in a square shape; this one also includes a parasitic element.. Loop antennas may be in the shape of a circle, a square or any other closed geometric shape that allows the total perimeter to be slightly more than one wavelength.
Diagram illustrating how isotropic gain is defined. The axes represent power density in watts per square meter. is the radiation pattern of a directive antenna, which radiates a maximum power density of watts per square meter at some given distance from the antenna. The green ball
A discone antenna is a monopole version of a biconical antenna, in which one of the cones is replaced by a disc. It is usually mounted vertically, with the disc at the top and the cone beneath. It is usually mounted vertically, with the disc at the top and the cone beneath.
