The geometrical size and radiation loss of the triangular patch are reduced simultaneously by loading both horizontal and vertical slots. The resonant frequencies of two degenerate modes can be easily controlled by varying the dimensions and positions of the slots. A two-pole dual-mode filter operating at 3.94 GHz with a fractional bandwidth of 4.3% is designed, fabricated, and measured. The measured results verify well the theoretical predictions., copyright(c)2006 IEICE 許諾番号:07RB0174  http://www.ieice.org/jpn/trans_online/index.html, text, application/pdf}, pages = {503--508}, title = {Dual-Mode Bandpass Filters Using Microstrip Slotted Equilateral Triangular Patch Resonators}, volume = {E89-C}, year = {2006}, yomi = {マ, テツオウ and HU, ウェイリアン and コバヤシ, ヨシオ} }
