Design and Analysis of Metamaterial Patch Antenna 5G and X Band Applications

In the proposed work, a design and investigation of Microstrip patch antenna for ku band operation is recommended. A square patch metamaterial antenna was designed and fabricated using Arlon AD 1000 (tm) substrate. The proposed antenna is designed to be compact in size, higher gain and suitable for higher frequency bands. The antenna ground layer is imposed by metamaterial structure, the top radiating layer have square patch with three reflectors of pi ( π) shape. The dimension of the radiating patch is 4.6 mm×4.6 mm and the reflectors are 7 mm×0.5 mm, 0.5 mm×6.3 mm, 0.5mm×6.3mm. This antenna has been modeled with square patch and pi ( π) shape reflectors to achieve precise narrowband operation. The measured results shows that the square patch metamaterial antenna has a return loss of -15dB at 15.5GHz and -23dB at 19.1GHz, meanwhile it has a gain of 2dB and directivity of 3dB. This antenna was designed for satellite applications such as live broadcasting, naval satellite downlink application, etc.
