English Abstract

This research proposes a new antenna design for gain and bandwidth enhancement of the slotted bowtie microstrip antenna using the principle of partial substrate removal.

This new design is a lightweight and compact one that is suitable for broadband communications due to its high gain and wide bandwidth.

The slotted bowtie shape achieves the required wide bandwidth without increasing the microstrip size.

This antenna was designed to achieve a bandwidth of more than 5 GHz.

Furthermore, the gain of the bowtie antenna was enhanced by more than 2 dB due to the loss reduction in surface waves by using partial substrate removal.

ANSOFT’s High Frequency Structure Simulator (HFSS) which is based on finite-element method (FEM) was used for the design and the simulation of the antenna.

The standard antenna parameters such as gain, return loss, and radiation patterns were obtained and plotted.
