Abstract : In this work, we have presented microstrip low profile patch antenna at Millmeter wave (mmWave) for 5G and future communication. There are two designs presented in this work. The first, we designed a dual band in 5G new radio (NR) specified frequency bands of 27 GHz and 37 GHz. We achieved the design with maximum gain of 8 dB. In the second design, we modified the structure to obtain multiband; again, in the International Telecommunication Union (ITU) specified possible bands for mobile communication. The design was optimized for 5 different bands that is, 28 GHz, 35.5 GHz, 41 GHz, 51 GHz and 60 GHz. We obtained reasonably good bandwidth in each band. The basic patch dimension is 12.5 × 10.1 mm2. In order to increase the gain of the basic element, the array of antenna is designed. Linear array with element up to 10 is designed and simulated. It is observed that an increase in the gain of around 3 dB gain is achieved. On optimization, it is found that with 6 element array the performance is relatively better on both basic bands.
