Compact size dual-band loop array antenna

Abstract

This paper describes alternate way to generate dual band using loop within loop technique to confine the size of array. Simulated results show that antenna is tuned to 400 MHz with return loss of -13 dB and at 615.5 MHz with return loss of -31.6 dB. Lower band is of 10 MHz and upper one is of 14 MHz Antenna is fed with long feed line so is compatible with 50 Ohm line.
