Abstract

This paper presents the numerical simulation of a low-profile dual frequency loaded U-antenna for 3.5 GHz WiMAX and 7.5 GHz military satellite communication applications. The antenna has a very compact size of 23.5×14 mm ² and provides a bandwidth of 340 MHz (3.4 GHz-3.74 GHz) and 570 MHz (7.23 GHz-7.8 GHz) in the two different resonant modes. The antenna provides maximum gain of 7.51 and 3.14 dBi respectively at S ₁₁ <; -10 dB. It also provides almost omnidirectional radiation characteristics and excellent impedance matching in the operating bandwidth.
