PULSE WAVE PROPAGATING IN COPLANAR WAVEGUIDES (CPWS) ON LTCC SUBSTRATES

ABSTRACT: The propagation of pulse waves in coplanar waveguides (CPWs) is investigated, and these CPWs are assumed to be fabricated on a single-layer low- temperature co-fired ceramic (LTCC) substrate. The input pulse wave can be a Gaussian pulse or a sinusoldally modu-lated Gaussian pulse. Based on the standard Galerkin 's method in the spectral domain, combined with fast Fourier transform (FFT), the pulse waveform and delay in CPWs are demonstrated and compared for, No. 1, April 5 2003 a second plate, oriented orthogonally to the primary planar ele-ment, thus producing a crossed planar monopole (CPM), which is simpler to produce and has lower cost than a conical monopole. In this paper, further measurements have been made on this element. ANTENNA GEOMETRY AND IMPEDANCE PROPERTIES The simple planar monopole consists of a planar element that is fed using an SMA feedprobe. The planar elements were con-structed using a 0.2-mm-thick copper sheet and the groucdplan
