An ordinary patch antenna can be modeled as a simple resonance LC parallel circuit. This means that the resonant frequency may be lowered if the patch has slot cuts to increase the inductance L without affecting the parallel C. This communication pre

A method for miniaturizing a chip antenna is presented in this communication. It uses a folded meander line and therefore the length is half. Also, two upper and lower loading patches are used to improve the performance of the chip antenna. The chip

To improve the computation efficiency in analyzing large microstrip antenna arrays over a wide frequency band, we developed a wideband closed-form mutual impedance formula and a full wave analysis-based network method. In this method, we first divide

Amplitude and phase weighting at the subarray outputs alone causes grating lobes (GLs) in the array factor. A combined approach to disrupt the periodicity in the array is proposed to reduce the GLs. In this approach, three measures are simultaneously

Rectangular waveguide (RW) with sidewalls of vertical conducting cylinders (i.e. SIW, substrate-integrated waveguide) becomes popular with the advent of low-temperature co-fired ceramic structure; its analysis is usually numerical, or modal, leading

The novel folded substrate-integrated waveguide (FSIW) is 50% narrower than the substrate-integrated waveguide, but both have similar propagation characteristics. This paper derives the analytical formulas of propagation and cutoff characteristics of

Currently, about 80% of drinking water in Hong Kong is abstracted from The East River (Dongjiang) that is located in the mainland side of China. Literature records and monitoring results of 2000-2001 confirmed that the lower section of the Dongjiang

Capacitance formulas of the microstrip line are usually curve-fitted from numerical solutions, resulting in multiple arbitrary coefficients and multiple equations. Such complexity in equations obscures their physical insight. By using the novel techn

Fringe field effect is equivalent to an extension in size of an RF patch, either as resonator or as antenna. A CAD formula for this extension is derived from DC capacitor and is shown to be applicable for all practical thickness and permittivity er o
