# Microstrip Patch Antenna calculator | Patch Antenna Formula

This Microstrip Patch Antenna calculator calculates patch length and width. This patch antenna calculator uses microstrip dielectric, height and frequency for calculation.

Microstrip line is most popular for antenna designs due to due to its Smaller size, Ease in fabrication and easier troubleshooting. Hence microstrip patch antenna found its place in mobile phones and other rf circuit designs requiring constained antenna devices. The patch antenna calculator calculates length and width as outputs and requires inputs such as RF center frequency, dielectric constant and height of substrate.

Center Frequency, MHz (input1) :

Dielectric Constant (input2) :

Height of substance, mm (input3):

Width of Microstrip patch antenna, mm (Output1):

Length of Microstrip patch antenna, mm (Output2):

Ground plane dimention(Lg), mm (Output3):

Ground plane dimention(Wg), mm (Output4):

Example of Microstrip patch antenna calculator:
INPUTS :
Centre frequency (Fo)=1800MHz
Dielectric Constant (er)=11.9
Height of substrate (h)=1.5mm
OUTPUTS:
Patch width= 32.81 mm
Patch Length= 24.05 mm
Ground Plane Lg= 33.05 mm
Ground Plane Wg= 41.81mm

## Microstrip Patch Antenna Calculator Formula

Following equations or formula are used for this microstrip patch antenna calculator.

Microstrip patch antenna is used in mobile handset due to simple look, lower cost, small size and light in weight. This antenna does not take any much extra size and can be etched on the same mobile PCB itself. It covers microstrip based DCS band design example of mobile patch antenna.

Microstrip line is used to carry Electro-Magnetic Waves (EM waves) or microwave frequency signals. It consists of 3 layers, conducting strip, dielectric and Ground plane. It is used to design and fabricate RF and microwave components such as directional coupler, power divider/combiner, filter, microstrip patch antenna, MMIC etc. Refer Microstrip line basics >> and Microstrip line types >>.
