To reduce polarization mismatch loss found in linearly polarized antennas there is a need to implement circularly polarized antennas. In this thesis, the impedance and axial ratio bandwidths of circularly polarized antennas are increased which increases the effectiveness of the antenna by eliminating the need for multiple antennas to cover the same bandwidth. In this thesis a comprehensive background on antenna parameters is conducted to show losses in the antenna design and propagation path between receiver and transmitter antennas. A novel wideband, circularly polarized, bow-tie antenna and a frequency reconfigurable, electrically small, circular polarized antenna are presented in this thesis along with a 60 GHz propagation effect study in indoor environments.
