This paper presents a single-patch broadband microstrip antenna: the E-shaped patch antenna on a single-layer foam substrate is investigated. The broadband mechanism is explored by investigating the behavior of the currents on the patch. Bandwidth enhancement of the antenna is achieved by inserting two parallel slots into its radiating patch. The effects of the following design parameters: the slot length, width, and position are optimized to achieve a broad bandwidth. Finally, a 32% E-shaped patch antenna, resonating at wireless communication frequencies of 1.5 and 2.9 GHz, is designed. The antenna was designed using IE3D software.
