Design of U-Slot Microstrip Patch Antenna for Wireless Applications

We have been using antennas for wireless communication for several years and looking to reduce noise at increased information rate and fast response at low cost in Wired communication. Nowadays, new technologies are evolving in communications where Microstrip antennas are in use due to compact sizeable compared to typical antennas and easy installation. Wireless communications have established extensive and prompt modernization, specifically in the centre of the past two generations. The upcoming concept of the individual communication structure intends to furnish data communications at all time over the world. The authors have presented a U-shaped Slot loaded patch antenna for the wireless communication range in this paper. The presented patch antennas have high accuracy in transmitting the information rate. Therefore, microstrip patch antennas are persistent competitors for numerous wireless communications application programs. This paper presents a design, maximization, and simulation of a dual-band amended U-slot microstrip patch antenna for WiMAX/WLAN application. The operational characteristics are in the range of 2.45-2.57 GHz and 5.09-5.27 GHz range. The radiating patch fabricated on the Rogers RT/duroid 5880 substrates of dielectric constant of 2.2. The coaxial feeding technique connects the antenna with a 50Ω impedance. The presented u-slot antenna results return loss of -19.5 dB at 2.5 GHz and -30 dB at 5.27 GHz.
