Design and Analysis of Dual Band Microstrip Circular Patch Antenna
Author: Sudarshan Kumar Jain
Abstract: In this paper a dual band microstrip circular patch antenna with high gain is proposed. The antenna is designed at a frequency of 2.4 GHz and it has dual band characteristics. Due to the dual band characteristics, antenna can be used for the two resonant frequencies. The microstrip line feeding method is used here to energize the designed dual band antenna. Voltage standing wave ratio (VSWR) of the designed circular patch antenna is less than 2. The different characteristics of the antenna such as return loss(S11), gain, bandwidth, directivity, radiated field and VSWR is analysed for the two substrates such as Rogers RT/duroid 5880 and Arlon AD250 having different dielectric permittivity. The gain of the designed antenna is 6.93dB and 7.12dB using Arlon AD250 and Rogers RT/duroid 5880 respectively.
