How do I increase the range of my RF transmitter?
To increase the range of a transmitter one can either increase the power output, use a better antenna with more gain or place the antenna in a better location such as with FM broadcast or commercial 2-way radio place the antenna at much higher height. Same can be done at the receiving end.
What is the size of antenna?
The size of the antenna comparable to the wavelength of the signal (at least `lambda//4`) . So that the antenna properly senses the time variation of the signal . For an e.m waves of frequency 20 kHz, the wavelength `lambda` is 15 km . Obviously such a long antenna is not possible to construct and operate .
What is RF design?
Introduction to RF Circuit Design RF circuits are designed to mimic the standard circuit elements and some simple integrated circuits by constructing structures using printed elements on a circuit board design. RF circuits can appear a bit foreign as they do not always use off-the-shelf components.
What is RF antenna?
An antenna is a specialized transducer that converts radio-frequency (RF) fields into alternating current (AC) or vice-versa.
How to design a simple antenna?
Gain: In this menu,you can find antenna gain for three variations of Yagi antenna namely,VK3AUU,WA2PHW,and DJ9BV.
How to increase antennas signal strength through design?
– OMNIDIRECTIONAL PATTERN GAIN ANTENNAS. To achieve a greater increase in this circular (or omnidirectional) pattern, we can stack multiple vertical dipole antennas above each other, as shown in figure 3. – APERTURE. Aperture, or beam width, determines the gain of an antenna. – SPACING OF DIPOLE ELEMENTS. – THE BOTTOM LINE OF ANTENNA DESIGN.
How to design an antenna matching circuit?

What is the importance of antenna design?
Common Terms. Antennas calibrated under NFSAF over a conducting ground plane are specified with horizontal polarization,R=10 m,h 1 =2m,and h 2 =1 to 4 m.
