The characteristics of a small antenna using an H-shaped microstrip patch antenna is analyzed. Significant reduction of antenna size can be realized when the H-shaped patch is used instead of the conventional rectangular microstrip patch antenna. The effect of various antenna parameters like substrate height, radius of shorting post and feed point are analyzed and their effect on return loss is shown.
A theoretical investigation of IMPATT diode integrated annular ring microstrip antenna is proposed. In which the resonance frequency is controllable by means of bias voltage of IMPATT diode without altering the radii of annular ring. The investigations based on cavity model are carried out for the various feed location and reverse bias voltage and maximum frequency agility of 10 MHz is achieved with...
Theoretical investigations conducted on gap coupled annular ring microstrip antenna is found to exhibit frequency tunability with the gap. The various parameters of the antenna such as input impedance, VSWR, return loss and radiation pattern have been investigated as a function of gap length and feed point. It is found that the various parameters of gap coupled microstrip antenna dependent heavily...
A theoretical analysis of compact slot loaded shorted patch using equivalent circuit concept is presented. By controlling the slot length, the two resonant frequencies f10 and f30 is tunable in the range of 1.44-1.39 GHz and 4.44-4.39 GHz respectably. By comparing the proposed antenna with the reference patch antenna fed by probe achieved size reduction of 50%.
