Nonagreement of forward echo and return loss

Electronics Letters, 1976
Mathematical models of coaxial cables allow the derivation of relationships between the forward echo and return loss due to the periodic nature of the structure. Experimentation has served to demonstrate that the prediction of forward echo from return-loss information is limited in its application for practical cables.

Penggunaan Dual-Layer Substrate untuk Meningkatkan Bandwidth Antena Mikrostrip pada Frekuensi LTE

Jurnal Nasional Teknik Elektro, 2018
Narrow bandwidth is one of the problems in a microstrip antenna. Bandwidth enhancement is proposed by applying dual-layer in the substrate. The bottom layer is made from a single-layer circular microstrip antenna design by applying the formula to get an ...
