Abstract : This final report covers the investigation of two microstrip antenna types, the microstrip slot radiator and the microstrip dual folded dipole. The slot dipole is a wide bandwidth (20%), low efficiency (20%) radiator suitable for use in for use in serial slot arrays, and is subject to beam steering with frequency. Array tests showed 20 dB sidelobes, and methods of varying slot susceptance are discussed. The dual folded dipole (DFD) is a 10% bandwidth designed on dual dielectric substrates; the lower substrate can be a high-K dielectric useful for MMIC front-end designs. A noncontacting coupling is made to the DFD radiator. Tests show a tested gain of +7.3 dBi. Keywords include: Microslot antenna, Conformal antenna, Conformal arrays, AWACS, Radio camera, Beamforming, Airborne arrays, Airborne sensors.
