Abstract
Electrically small antennas are researched heavily throughout electromagnetic literature due to their practicality. Antennas need to be able to fit into small places such as cell phones. However, the reduction of antenna size comes at a cost in decreasing the impedance bandwidth and radiation efficiency of the antenna. This research aims to find solutions to having sized-reduced antennas while enhancing both the impedance bandwidth and radiation characteristics of the antenna. First, the size reduction of a dual-element dipole is analyzed. Dual-element dipoles are known to have impedance bandwidth enhancing properties along with the ability to have different radiation modes. Next, this idea will be improved upon by implementing the planar version of that wire antenna to further enhance the impedance bandwidth. Planar antennas are also more practical as they can be incorporated into printed circuit boards. Finally, a tuning method to combine the first harmonic frequency with the resonant frequency is given to create a sized-reduced wideband dipole antenna. All antenna designs have experimental validation backed by simulated results.
