Greetings Everyone,
I need to design a planar 100-500 MHz band Antenna in a small form factor., Kindly let me know which type of antenna can be used or any reference which can be useful.
Thanks in advance.
There are many different designs for 100-500 MHz planar antennas, but some of the most common include:
- Patch antennas: Patch antennas are simple to design and fabricate, and they can be made very small. However, they have a narrow bandwidth and low gain.
- Dipole antennas: Dipole antennas have a wider bandwidth than patch antennas, but they are larger and more difficult to fabricate.
- Spiral antennas: Spiral antennas have a very wide bandwidth and can be made very small, but they have a complex design and are difficult to fabricate.
- Printed circuit board (PCB) antennas: PCB antennas are a type of planar antenna that is easy to fabricate and can be integrated into electronic devices. However, they have a narrow bandwidth and low gain.
The best type of planar antenna for a particular application will depend on the specific requirements of that application, such as bandwidth, gain, size, and cost.
Here is an example of a simple patch antenna design for the 100-500 MHz frequency band:
Materials:
- FR-4 substrate (dielectric constant = 4.6, thickness = 1.6 mm)
- Copper tape (0.5 mm thick)
Dimensions:
- Patch width = 65 mm
- Patch length = 30 mm
- Ground plane width = 100 mm
- Ground plane length = 50 mm
- Feed line width = 3 mm
- Feed line length = 10 mm
Construction:
Tuning:
The antenna can be tuned by adjusting the length of the feed line. To tune the antenna for maximum gain, connect a VSWR meter to the feed line and adjust the length of the feed line until the VSWR is minimized.
This is just a basic example of a planar antenna design. There are many other variations and designs that can be used. For more information on planar antenna design, please consult a reference book on antenna engineering.
Methods of beam shaping as subject may be compatible with objective.
best choice is wire based antenna, patch antenna will turn out to be of a very big size..
Nayab Gogosh My requirement is planar antenna . There is no limitation for patch only , you can suggest any other planar antenna.
Hello,
Few papers are attached.

Thanks,
I would consider magnetic loop, however it must be tuned to particular frequency e.g. https://m0ukd.com/homebrew/antennas/magnetic-loop-antennas/
Smrity Dwivedi Thank you for your valuable suggestion. I have seen multiple papers of this author but after simulating them I found that none of the paper which is claiming for < 1 Ghz frequency are all fake or may be he hides the information. So it is not useful.
