Design and implementation of wideband terahertz on-chip antenna for terahertz frequency application

Abstract

Microstrip antenna have been adaptable because of their appealing features such as low profile, low weight, and low cost, microstrip antennas have been widely used in modern wireless communication, satellite communication, 2G/3G mobile services, marine or land vehicle navigations (GPS), wireless LAN access, and many small devices embedded with Bluetooth, UWB, Zigbee, DVB, and so on. Confirmability, as well as compatibility with MMIC designs. This paper presented a multi-band antenna for multifunctional wireless message employing a defective ground plane. The antenna is employed in twelve slots in a ground plane, and they function as electronics band gap tuning, allowing us to tune the frequency for a variety of wireless communication applications. The suggested design operates in four bands: 4.6 GHz to 5 GHz, 5.2 GHz to 5.5 GHz, and 5.6 to 6.2 GHz.and 6.5 to 8.9 GHz. The exciting patch, also known as a radiator patch, is made up of a parasitic and rectangular slot, as well as a segregated ground and exciting patch that runs through a FR4 dielectric substrate. The radiation patch and ground are linked by a 0.5 mm hole. A design's structure is concise and straightforward. A proposed antenna has dimensions of 20*24*1.5 mm3 with regard to wavelength 0.30, where 0 is a free space wavelength. The proposed design is appropriate for numerous wireless communication protocols, including WLAN, WiMAX, and X band applications. A proposed antenna has a bandwidth of 61%, a VSWR of 2, a minimum return loss of −20dBi, and a directivity of 7dBi.
