Rectangular Microstrip Patch Antenna #meeting3

In this meeting,we will start t draw and design the the rectangular microstrip antenna with the given parameter:

Design specifications

Design Parameters

·         Operating Frequency,  f_o  = 2.4 GHz

·         Fractional Bandwidth > 1% and VSWR < 2%

·         Input Impedance, Z_in =  50 ohms 

·         Linear Polarization

·         Half-Power-Beam-Width (HPBW) > 120 degrees

Substrate Parameters

·         Lossy material of FR-4

·         Relative Dielectric Permittivity, ɛ_r  = 4.4

·         Substrate Thickness, h  = 1.6 mm

·         Conductor Thickness (Copper), t  = 0.035 mm

·         Substrate Dielectric Loss Tangent, tanδ  = 0.025

·         Maximum Substrate Area depends on the geometry of the patch antenna not exceed 10x10cm

Feeding method

·         Microstrip line with a characteristic impedance Z_o = 50 ohms     

The value for the length and width of patch and substrate is calcualted and checked by using online calculator as shown:

The design of the rectangular microstrip antenna is drawn :

TheS11 and VSWR graph is simulate and obtained as shown.But in order to get the optimised performance,we will like to change and optimised the parameter by changing the lentgth and width of the patch and we will done it by the next meeting.
