Design and Implementation of 2x1Microstrip Patch Antenna Array for with Parasitic Element Structure Isolation for 4G Applications

الملخص

Abstract: For 4G-LTE applications, this study presents an integrated design with an array antenna system. With cut rectangular shape and a slightly sloped ground, a two-shared radiator for 2.1 GHz is presented. A 2-element slot is included in each port of the suggested design. Two antenna system components are housed on a single, inexpensive FR4 substrate that is fed by a 50 microstrip. In order to construct tiny antennas for communications, it is essential to provide enough antenna isolation. The findings show that the antenna has a better than 10 dB return loss at 2.1 GHz. The cancellation of current between any two antennas is a novel method for reducing mutual coupling. The suggested antenna achieves greater isolation than -26.7 dB between a pair of inputs.  Additionally, the suggested antenna has a compact size reduction of around 60% compared to traditional patch antennas operating at the same frequency. This is due to the tiny spacing between antenna pieces.
