This paper presents the design of a rectangular Microstrip Patch Antenna (MPA) intended for operation at 2.4 GHz frequency, predominantly used in wireless communication. The proposed MPA, designed on an FR4-Epoxy substrate using microstrip line feeding approach, was simulated High-Frequency Structure Simulator (HFSS). primary metrics evaluated included return loss, gain, Voltage Standing Wave R...

The paper presents the design of patch antenna that can operate on a triple band 2.4GHz, 4.6GHz, 5.5GHz. The shape of the patch resembles an English alphabet `E`. Two parallel slots are incorporated to get the shape of ‘E’ and the dimensions were optimized using CST Microwave Studio EM Simulator. Different parameters like return loss, VSWR, Radiation pattern in 3D are presented.

A simple microstrip line fed antenna with thin substrate is proposed in this letter for multi-band wireless applications. The multi-band characteristic was achieved by overlapping an annular slot antenna with two concentric fan shaped patches. The antenna demonstrates three wide impedance bandwidths (VSWR ≤ 2) of 36.3, 63.4 and 25.5% with stable polarization and radiation characteristics.

This paper reports the design of a wide band planar fed, planar conical loop Antenna. Parametric studies have been carried out to arrive at the optimum antenna dimensions to have a wide impedance bandwidth (VSWR<2). Experimental results confirmed the wide impedance bandwidth.
