Abstract

In this paper, the design and simulation of a Log Periodic T Antenna is presented. T antennas are generally small sized antennas used in VLF, LF and shortwave bands. These antennas can be used in a wide variety of applications due to their ease of designing and simplicity but are restricted to small bandwidth, low efficiency and low frequency band applications. To overcome the deficiencies’ of this antenna, Log Periodic T antenna (LPTA) is proposed. The proposed antenna can be used in higher frequency band applications (S band) and has a broad bandwidth. The proposed T-antenna is implemented by means of a patch. The substrate is chosen to be RT Duroid. The antenna dimensions are calculated using Transmission Line model. The antenna layout is simulated in Agilent’s Advanced Design System (ADS) simulator.
