SIMULATION OF RECTANGULAR MICROSTRIP PATCH ANTENNA FOR RANGE OF Ka BAND FREQUENCY
In today’s worlds the demand of data transmission with high bandwidth and speed is increased to overcome which technology of communication is moving towards 5G due to their compact features. This 5G uses the mmwave frequency range in this experiment we design a rectangular microstrip antenna of patch type and simulate it. In this research, a 38 GHz frequency range from Ka band is taken. The compact structure of patch antenna diameters is of 6.285 mm × 7.235 mm × 0.5 mm. but the resonating frequency range is 27.954 GHz to our proposed antenna having a loss of that is return loss of about of -13.48 dB, and with 900MHz bandwidth, also 10dB gain and 80% efficient is obtained after simulation. For matching the patch of radiation and feed line of 50 ohm microstrip we use insect feed technique of transmission line. In fabrication of this antenna lithography technique is used on Roger RT Duroid 5880 substrate which has high tolerance with tangent loss of 0.0009, height is about 0.4mm and dielectric constant of 2.2 is used. By using CST Microwave Studio we simulate our design of antenna in proposed geometry.
