What are patch antenna used for?
What Does Patch Antenna Mean? A patch antenna is a low-profile directional radio antenna that is used for indoor locations covering single-floor offices, stores and small studios. It is mounted on a small, rectangular, flat surface and consists of two metallic plates placed upon each other.
How does a patch antenna radiate?
The patch’s radiation at the fringing fields results in a certain farfield radiation pattern. This radiation pattern shows that the antenna radiates more power in a certain direction than another direction. The fringing fields at the radiating edges can be viewed as two radiating slots placed above a groundplane.
What is MIMO patch antenna?
The MIMO antenna has four square-shaped patches with two slots in each that are interconnected with each other using four strip lines printed on a substrate of Rogers Duroid RT 5880 with relative permittivity of εr = 2.2 and tangent loss of δ = 0.0009.
Is a patch antenna directional?
A patch antenna (also microstrip) is a directional low profile, low-cost antenna that can be fabricated onto a flat surface, including a Printed Circuit Board (PCB).
Why S11 is taken below?
S11 below -10dB means at least 90% input power is delivered to device and reflected power is less than 10%. This value is sufficient for many applications. S11 is return loss of the antenna and one of the important parameter of antenna testing .
What are patch antennas made of?
A patch antenna is a type of antenna with a low profile, which can be mounted on a surface. It consists of a planar rectangular, circular, triangular, or any geometrical sheet or “patch” of metal, mounted over a larger sheet of metal called a ground plane.
What is 5G antenna?
5G will use ‘massive’ MIMO (multiple input, multiple output) antennas that have very large numbers of antenna elements or connections to send and receive more data simultaneously. The benefit to users is that more people can simultaneously connect to the network and maintain high throughput.
How many antennas does a 5G phone have?
That means many, if not most, new 5G phones will have four antennas for the cellular bands. These antennas will likely have some automatic antenna-tuning capability. Also in the mix are one or two antennas for Wi-Fi and Bluetooth. Since both wireless technologies operate at 2.4 GHz, it’s possible to share an antenna.
