This thesis is about two kinds of small broadband antenna designs. One is a small broadband antenna composed of a dual-meander folded loop and a disk-loaded monopole. Its size is 0.1λ × 0.1λ × 0.098λ at the center frequency of 1.495 GHz.

A circularly polarized (CP) cavity-backed annular slot antenna for GPS receiver is designed to operate in both the L1 and L2 bands of the Global Positioning System (GPS). The measured impedance bandwidths with VSWR less than 2 are 3.7% (1.19-1.235 GH

A small broadband antenna composed of a dual-meander folded loop and a disk-loaded monopole is designed and measured. Measurement results confirm a fractional bandwidth of 10.8% with the voltage standing-wave ratio (VSWR) less than 2. The measured ra

A deterministic phase-encoded encryption system is proposed. A lenticular lens array (LLA) sheet with a particular LPI (lenticular per inch) number is chosen as a modulator (key) instead of the random phase molator. The suggested encryption scheme is

This work presents a simple approach for arbitrary phase-step digital holography using two holograms without ambiguity. Using this approach, a magnitude-contrast image is reconstructed without dc term and twin-image blurring, but the phase-contrast i

This work presents a novel physical mean scheme for correcting the image curvatures introduced by a micro-objective (MO) lens in digital holographic microscopy (DHM). The image curvature due to the quadratic phase term is commonly referred to as defo
