U-Slot Cut Rectangular Microstrip Antenna with a Large Ground Plane and a Thin Substrate
Authors: , , ,
Abstract: It is very well known that the Rectangular Microstrip Antennas (RMA) are narrowband, but it is
possible to enhance its bandwidth by cutting slots inside the patch. Some slots variations have been used to
improve this important feature in modern mobile radiocommunication systems. Although U-slot antennas are
employed in broadband applications, it is very important to consider the usage of a thick substrate with a low
dielectric constant. In this paper, an RMA with a U-slot is presented and analyzed, which was built in a Printed
Circuit Board (PCB) with a thin FR4 substrate for 800 MHz to 900 MHz. The PCB that is necessary to fabricate
the antenna is very low cost and it is conformable in many mobile terminals. The antenna was simulated in HFSS
and measured using return loss and its antenna patterns
