Microstrip patch antenna with concave bottom layer on two sides

Abstract

A microstrip patch antenna with a two-sided concave substrate can be used simultaneously in all WLAN, 4G LTE and 5G wireless technologies, especially in the frequency range 4940-5600 MHz, serving in frequency bands determined by the standards the distinctive feature of which is; a lower base formed in a circular form on the horizontal axes with both surfaces concave on the vertical axis, the ground plane located in the lower part of the lower base and having a concave structure, the lower base to the top surface of the lower base with a frequency range can be adjusted and fixed in a single piece form that is built to work in a wide frequency range and the first slot and the second slot that contains a patch, the impedance matching line electrically connected to the patch so that it is one piece with the lower base and patch.
