Millimeter-wave Wide Aperture Antenna Implementation and Small Dual-Band Antenna Design

This thesis is aimed at discussing the performance of millimeter-wave antennas for SOC/SOP purposes.
The first part of this thesis is about wide band antennas designed to operate at 40GHz ~ 48GHz implemented on LTCC and GaAs substrates. The performance of these antennas would set the footstone for on-chip antenna design in the future.
The second part of this thesis is discussing antenna bandwidth enhancement design and small size antenna design. The original bandwidth of folded slot antenna (8% ~ 11%) is enlarged by introducing an inductively coupled slot antenna. The bandwidth of this new antenna is about 27%. Also, a new small-sized dual band antenna is proposed in this thesis. The small antenna operating at 2.4GHz/5GHz ~ 6GHz, which covers the 802.11a/b/g bands, is very suitable for indoor communication system.
