How does the layout of a chip affect antenna performance?

How does the layout of a chip affect antenna performance?

Chip Antenna matching and radiation pattern performance can be dramatically affected by the design/layout of a circuit. Antenna mounting, the antenna’s position relative to circuit mismatches, the antenna position relative to adjacent components and ground planes all can affect antenna performance.

Why is it important to have antenna matching for Bluetooth?

Bluetooth and Antenna Matching Introduction Antenna matching is an important aspect of any RF system. A properly designed and matched antenna increases the operating distance of the wireless product. Well matched antennas can transmit more power from the radio – therefore transmit over longer distances.

Do you have to match antenna to antenna?

The PRoC BLE, PSoC 4 BLE, and PSoC 6 BLE 2.4-GHz radio must be carefully matched to its antenna for optimum performance. Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it.

What kind of matching component is needed for 2.45 GHz antenna?

For the antenna to resonate at 2.45 GHz when mounted as shown here, the in-line matching component of 1.2 pF is required. The matching component may be slightly different than that shown depending on distance to ground plane, dielectric constant of PCB, and PCB material thickness.

Where is the signal path from the VNA to the antenna?

Now that the VNA is calibrated “to the Lump” we can measure the raw impedance of the antenna and the surrounding PCB. To do this remove the short at location Z3 and insert a short in the series location Z2. The signal path is now direct from the VNA to the antenna.

How are VIAs used in a chip antenna?

Connect the edge portion of ground planes (the ground plane surrounding the microstripline feeding the antenna to the bottom ground plane layer) with many through holes (vias). These through holes minimize the electric fields which are generated at the edge, minimizing the effects on the antenna performance.

Which is an example of an antenna tune up?

Antenna tuning is an illusive process, which combines complex mathematical theory and heuristic methods. This paper endeavors to inform Engineers how to tune, or match, antennas for s-band radios. This example matches a 2.4GHz chip antenna that could be used for ZigBee®, Wi-Fi®, or Bluetooth®Radios.

How big should the antenna be on a PCB?

More than 4 mm from the longer edge of the antenna (the antenna is mounted on the edge of a PCB, so there is no ground plane adjacent to one of the longer sides) The performance greatly deteriorates if the dimensions are less than the minimum dimensions mentioned above in 4.a and 4.b although the antenna still works.

How is an antenna connected to a breadboard?

The antenna is connected to the breadboard with copper wire. Use half a breadboard cable and connect it to one end of the copper wire. This can be done by twisting the copper together. The connection can be soldered together to make it more permanent.

How do you hook up a radio to a breadboard?

Plug the breadboard cable (with the copper wire attached) into the breadboard at coordinate 30a. Next, the end of the copper wire is twisted around the sanded part of the antenna. Use duct-tape to make the connection to the tube more secure. Turn on your radio and put it on channel AM 819 kH.
