DESIGN AND DEVELOPMENT OF A HIGH GAIN DISCONE ANTENNA FOR 4G LTE APPLICATIONS

This study offers the design and realization procedure of a broadband monopole antenna for use in communication applications between 670 MHz-2750 MHz. the proposed monopole antenna comprises a low-cost discone antenna which has a relatively high gain value over a wide operation band. Firstly, the performance of the antenna is studied by changing the value of design parameters. Effect of each design parameter on return loss (S-11) and gain characteristic of the antenna design is observed and the optimal design parameters are taken. Both simulation and measurement results of the proposed antenna design show a matched bandwidth and a return loss of less than -10 dB in the desired operation band of 670 MHz and 2750 MHz. as it can be seen from both simulation and experimental results, the proposed discone antenna design is a suitable solution for broad-band wireless communication applications.
