Rectangular Meandered Wire Inverted F Antenna for UHF Applications

Abstract

This paper presents a rectangular wire inverted F antenna for UHF communication devices at 406MHz frequency. The proposed antenna provides a maximum gain of 2.5dB and return loss of 12 dB at 406MHz frequency. The antenna with its circular ground plane provides a near symmetrical monopole pattern. The proposed design reduces the overall size of the UHF antenna and allows the user to keep the antenna confined within the communication device unlike projecting monopole antennas.
