In this paper, analysis of a lower order and dominant mode of a rectangular microstrip antenna with a loading of the single shorting post has been presented. Microstrip line feed of 50 Ω impedance along one of the radiating edges with a single shorting post has been proposed for impedance matching. A detailed investigation of the rectangular microstrip antenna with and without single shorting pin...
This paper presents, a low profile hexagonal ring patch antenna for biomedical application at 2.4 GHz ISM Band. Dimensions of hexagonal ring patch antenna are based on their equivalence with annular ring patch antenna. This proposed antenna has been validated using simulation and experiments which gives accurate results.
A space-fed array fed by a proximity fed microstrip antenna for a broader bandwidth is proposed. The 1 × 3, 3 × 1, plus-shaped and 3 × 3 configurations are studied. A parametric study for varying distances between the fed-patch and the array is done and the optimum results for each configuration have been presented. A bandwidth of 1.1 GHz and a gain of 14.6 dBi is obtained in 3 × 3 space fed configuration.
This paper presents, a novel approach to calculate the resonance frequency of hexagonal ring microstrip antennas based on their equivalence with annular ring microstrip antenna. This proposed empirical formula has been validated using simulation and experiments which gives accurate results.
