An electrically small and low profile triple-band split ring antenna is presented. The antenna itself operates at three frequency bands of 430MHz, 680MHz and 990MHz. It is 100mm long which corresponds to λ/7 at the lowest working frequency of 430MHz. The antenna is placed over a small artificial magnetic conductor which works at 430MHz to form a very compact, conformal platform tolerant antenna. Significant...
A 450 MHz miniaturised split ring antenna is integrated with a small artificial magnetic conductor to form a very compact, conformal platform tolerant antenna. Both the antenna and the AMC utilise loading by discrete, lumped circuit elements to significantly reduce the size of the overall radiating structure. Tunablility of the structure is achievable by simply varying the loaded lumped capacitors...
A 450 MHz miniaturised split ring antenna loaded with lumped element capacitors is presented. The antenna is placed over a small artificial magnetic conductor to form a very compact, conformal platform tolerant antenna. Significant bandwidth and gain improvements are achieved for the combined structure when compared to the performance of the antenna alone. The overall thickness of the structure is...
A split ring antenna loaded with lumped element capacitors is presented measuring λ/9 at 450 MHz. It is placed over a small artificial magnetic conductor (AMC) to form a very compact, conformal platform tolerant antenna. The overall thickness of the structure is just 15.2 mm which is 1/44 of a wavelength at 450 MHz.
