Abstract


Non-directional antenna bays in FM broadcast applications were designed to exhibit radiation characteristics that conform to broadcast standards. However, the metallic tower where these antennas are mounted and secured is not considered during the development process. Knowing that the radiation characteristics of antennas are affected by the metallic tower, it is the aim of this paper to present the compliance of the side-mounted Circularly Polarized Antenna (CPA) to broadcast standards. The CPA compliance to requirements on polarization components, pattern circularity and bandwidth is specifically presented. Results of numerical analyses using an advanced antenna simulation software show that the radiation characteristics of the CPA are severely altered by the presence of the tower and thus impairing its capacity to adhere to the said broadcast requirements. Some adjustments on the CPA structure are needed to improve its performance.
