Circuit Board Dipole Antenna Structure With Impedance Matching Trace

The Smith Chart impedance matching data points 1, 2 and 3 respectively, in Figure 4 (a), were obtained by fixing a central frequency of 868 MHz, thus generating point 1; then by drawing a series capacitance from point 1 to point 2 and finally drawing a shunt inductance from point 2 to point 3. This means the pulling of antenna’s impedance to the central matching point.

Printed circuit board dipole antenna structure with impedance matching trace. Patent number: 6943749 Abstract: A printed circuit board antenna structure for the transmission of radio frequency energy.

of the antenna impedance. Thus if Z 0 = Z a´ the antenna is perfectly matched to the transmission line and all the applied power is delivered to the antenna. Antenna matching typically uses both the Return Loss and the Voltage Standing Wave Ratio (VSWR) terminology. VSWR is the ratio of the maximum output (Input + Γ) to the minimum

the RF world. It can be made from a piece of wire, or a trace on a PCB. The basic half wave dipole antenna is a wire or trace with a length of lambda/2 and a slot in the middle where the antenna is fed. The impedance is around 73 ohms, and the directivity is 2.15 dBi. 4 Designing a Half Wave Dipole Antenna on a PCB

An antenna's effective electrical length can be changed without changing its physical length by adding reactance, (inductance or capacitance) in series with it. This is called lumped-impedance matching or loading.. For example, a monopole antenna such as a metal rod fed at one end, will be resonant when its electrical length is equal to a quarter wavelength, λ/4, of the frequency used.

11/07/2016 · Hi all, I have a confusion regarding impedance matching. Suppose I design a planar dipole antenna for 5 GHz and 50 ohm impedance. Now if I want to use the same antenna at 1 GHz is it theoretically possible to match the input impedance of the same antenna @ 1 GHz and get good results in return loss and other parameters ? Apologies if I am missing something obvious.

Making part of the antenna parallel to the metal ground plane introduces capacitance and detunes the resistive input impedance, making some sort of matching solution necessary. ... on the same side of a printed circuit board, as shown in Fig. 3.6. An ...

Antenna impedance relates the voltage to the current at the input to the antenna. This is extremely important as we will see. Let's say an antenna has an impedance of 50 ohms. This means that if a sinusoidal voltage is applied at the antenna terminals with an amplitude of 1 Volt, then the current will have an amplitude of 1/50 = 0.02 Amps.
