A Multiband Tree-shaped Microstrip Antenna for Wireless Communication
Keywords:Tree shape, Finite Ground, High Gain, Current distribution
In the modern world, wireless communications are growing very fast and changing the world of antennas. Conventional antennas are insufficient to meet the requirements in the field of wireless communications. The continuous evolution of wireless communication systems has added cost, size, bandwidth, gain, and polarization constraints to the antennas used. In this paper, the performance of the microstrip antenna is enhanced by overlapping the patch elements. A tree-shaped micro-strip antenna is presented here, in which the tree-shaped geometry emerged from five overlapping circles on the substrate. The proposed antenna could operate in the X and Ku bands. The antenna is resonant at 9.3 GHz, 10.07 GHz, 11.76 GHz, and 13.16 GHz frequencies and has various applications such as satellite communications, radar, terrestrial broadband, space communications, and amateur radio. The built antenna has an improved radiation pattern as compared to conventional antennas.
