Background
Nowadays, wireless technology increase rapidly. So needed a device antenna can support that.
Microstrip antenna are widely used because of the advantages such as low profile, light weight and and conformity. However, narrow bandwidth is main disadvantages of microstrip antenna.
Research Objectives
Design and implement Antenna wideband that work at range frequency 1.8 GHz- 2.4 GHz and covered several wireless technologies at that range.
Understanding the characteristic of parameter on antenna E-shaped which controlling the achievable bandwidth .
Previous Research
1. Antenna E-shaped Rectangular with achievable bandwidth 408 MHz (1440-1848 MHz.) and VSWR < 2.
2. Antenna E-shaped patch triangular with achievable bandwidth 350 MHz (1562-1912 MHz) and VSWR <2 .
Con’d
3. Antenna E-shaped patch circular with achievable bandwidth 642 MHz (1482-2124 MHz) and VSWR <2 .
4. Antenna E-shaped Triple band resonated at frequency 900 MHz, 1800 MHz and 2400 MHz

Antenna E-shaped
E-shaped antenna is the antenna which is formed from a rectangular microstrip modified by adding a slit on both edge it is meant to shift the resonance frequency.
Meandering Technique
Techniques to bending length of each line Antennas in order to make the antenna be Compact and shifting resonant Frequency so that the bandwidth becomes wider.

Conclusion
Antenna E-shaped can operated at range frequency 1800 MHz- 2400MHz
From the results of antenna measurements and simulation realization of ≥ 600 MHz bandwidth which already meet the initial specifications of the antenna design
Antenna radiation pattern is unidirectional Parameter of slit such as The slot Length (Ls),
Width, and Position feeding (Ps) are very important controlling achievable bandwidth.
Suggestion
need of improvement accuracy in making antenna so that the result of realization more able to come near result of simulation.
Creating E-shaped antenna using another substrate for example FR4 or duroid so that the smaller dimensions can be obtained without decreasing achievable bandwidth.
