Improved Method for the Prediction of Resonance Frequency of Triangular Microstrip Antennas

“…The calculated resonance frequencies f, for various modes of ETMSA using present method are compared with measured data [I] and reported methods [1][2][3][4] in Table I It is observed that the proposed method gives good overall agreement with the measured data. Recently, a generalized method has been proposed by the present authors to compute the resonance frequency of MSAs [7].…”

“…One method reported the resonance frequency of the ETMSA based on its effective side length and relative dielectric constant and compared it with experimental data [I]. Another method [2,3] equated the area of the ETMSA to an equivalent circular microstrip antenna (CMSA), and, then effective radius of the CMSA [2,3) was obtained. From this, the effective side length of the ETMSA is calculated by equating back its area with that of the expanded CMSA, which is then used in the final expression of its resonance frequency.…”

“…-L,-M ANY papers have been reported to predict the resonance frequency of an equilateral triangular micros trip antenna (ETMSA) using cavity model [1][2][3][4]. One method reported the resonance frequency of the ETMSA based on its effective side length and relative dielectric constant and compared it with experimental data [I].…”

Analysis and Design of Equilateral Triangular Microstrip Patch Antenna with Microstrip Feed

“…In this paper, we consider a microstrip antenna with Equilateral Traingle (ET) configuration with inset microstrip feed line as shown in Fig 1. The performance ofETMP antenna is similar to the performance of Rectangular microstrip patch antenna with an added advantage of physically being small. Probe feed is widely used, in the literature [1][2][3][4][5][6][7][8], for ETMP antenna. However, microstrip type feed structure suits better in array environment.…”

“…One of the important aspects of the antenna design is its resonant frequency. A number of techniques are available in [1][2][3][4][5][6][7][8] to determine the exact resonant frequency of ETMP antenna. The theoretical results presented in these works [1][2][3][4][5][6][7][8] are not in good agreement with the experimental data.…”
