The document summarizes a proposed research project on software defined antennas (SDA). The project aims to investigate a single reconfigurable structure with multiple radiating sections that allows frequency, polarization, and radiation patterns to be varied for different radio systems. The methodology will use different antenna elements like axial mode helix, normal mode helix, and inner rod to operate at frequencies including 1.6GHz, 150MHz, 400MHz, and 2.4GHz. The expected outcomes are antenna gains comparable to single antennas, omni-directional patterns, ability to tune over frequency bands, isolation between sections, and an effective switching method.

- 2. INDEX • Introduction about “Software Defined Antennas”. • Summary of the proposed project. • Background of Research Work. • Critical review of Literatures and identification of research gap. • Objectives of Research work. • Methodology or approach intended to be adopted in the execution of the research. • Expected outcome. • References.
- 3. Introduction on Software Defined Antennas (SDA) • The UWB antennas allow the software defined radio to receive a wide range of frequencies using just one antenna / element per reception site which is termed as “Software Defined Radios”. • SDA are a "notable" topic, suitable for inclusion in Research. SDA has received significant coverage in reliable secondary sources. • Two patents, in 2009 & 2004, and recent articles published in IEEE Journals. • U.S. Department of Defense has awarded a series of SDA research contracts.
- 4. Summary of the proposed project • Main summary is to investigate the feasibility of a single re- configurable structure comprising multiple radiating sections, described as a “Software Defined Antenna.” • It also allows frequency of operation, polarization and radiation patterns to be varied to suit different radio systems. • Which also provides with multiple input feeds, simultaneous operation of several radio systems from one unit.

Target Frequencies And Applications For The SDA- Table 1 Nominal Frequency Application Polarisation 75MHz Tactical VHF Linear, vertical 150MHz Tactical VHF Linear, vertical 400MHz Line of Sight Voice Communications e.g. TETRA or UHF Military Communications Linear, vertical 1.3GHz Video Downlink from manned aircraft or UAVs Linear, vertical 1.575GHz GPS RHCP 1.6GHz L-Band Satellite Communications e.g. Iridium RHCP 2.4GHz Line of Sight WiFi Network e.g. Tactical Information Systems Linear, vertical And much more frequency band
- 7. Background of research • The two main sections within this SDA design are: An outer helix. An inner, vertical rod. Fig. 2 EM Model of the SDA. The Method of Moments (MoM) technique was applied. The MoM is an accurate and rigorous tool and is often used as the benchmark for validation exercises of other EM codes.

Objectives of research work • To investigate the feasibility of a single re-configurable structure comprising multiple radiating sections. • To operate for various frequency of operation. • Various polarisation which suits for different radio systems. • Various radiation patterns which suits for different radio systems.
- 11. Methodology or Approach intended to be adopted in the execution of the research • Axial Mode Helix to be used for 1.6GHz • Normal Mode Helix to be used for 150MHz • Inner Rod to be used for 400GHz • Vertical Element to be used for 2.4GHz
- 12. Expected outcome: • Antenna gain commensurate with single antenna counterparts. • Omni-directional azimuth radiation patterns for the line of sight linear elements. • Ability to tune over a band of frequencies, not just the nominal spot frequencies listed above. • A need to satisfy the radio system requirements for isolation between radiating sections. • An effective method of switching and re-configuring the structure, noting specifically the need for switching • Speed, switch control power and RF power handling.
