“…Frequency independence suggests that the antenna should have good and similar performance in terms of the parameters like impedance, VSWR, and radiation pattern throughout the frequency band . Several log periodic arrays have been reported previously by researchers, such as rectangular patch array, slot antenna array, dipole array, and so on . But the major drawback of these arrays is their size.…”

A microstrip triangular‐ring antenna structure designed using the log‐periodic principle has been proposed. The antenna elements and the feeding networks have been designed and the antenna simulations are done using Ansoft HFSS software. Shorting posts have been used at the center of the edges of the ring to adjust the shift in the resonant frequency. The simulated and tested results show that the ring antenna with three posts resonated at the same frequency as the triangular patch giving an enhanced gain and a size reduction of 81%. A log periodic array of three triangular rings is also designed and analyzed which gives a good frequency independent behavior in the frequency range of 6.6–11.6 GHz. © 2014 Wiley Periodicals, Inc.

“…The bandwidth of the proposed antenna should cover the bandwidth of PD signals mainly from 500 MHz to 1500 MHz. Although many antennas such as log-periodic antenna [3], spiral antenna [4], and bow-tie antenna [5] can achieve a relatively wide bandwidth, their dimensions do not meet the requirements. Therefore a miniaturized wide-angle structure with gap and arm loading is introduced in this paper to meet both the size limits and bandwidth requirements.…”

An ultra high frequency (UHF) sensor antenna with metallic shell for PD detection has been proposed and experimentally studied in this article. The impedance bandwidth of the proposed phantom is considerably improved when the metallic shell is filled with radiation absorbing material, which is based on the simulation results by Ansoft HFSS. When the height of the RAM reaches 3 cm, the proposed antenna obtains a bandwidth from 800 MHz to over 1.7 GHz with VSWR<2.7, within which can effectively detect the PD signals.
