Design a Circular Slot Patch Antenna with Dual Band Frequency
Locale of research work indicates some basic concepts related to patch antenna. The techniques for increasing bandwidth of circular patch antenna are explained with other parameters. Patch antenna is basically used for wireless communication systems. Design a circular slot patch antenna of dual band frequency. Each type of antenna is good in their properties and usage. Antennas are those backbones also almost all that in the wireless communication without which the world could have not arrived at in this period of technology. The proposed micro-strip patch antenna has FR4 lossy as a dielectric substrate with thickness of 1.6 mm and relative permittivity εr is 4.3. The simulation results of directivity, gain, and return loss of designed patch antenna are determined successfully. It is designed the dual band frequency having a return loss −30 dB at 1.5 GHz and second one is −40 dB at 2.5 GHz, analyzed in CST software.
