A zigzag slow-wave line of double ridged waveguide belongs to the technical field of microwave vacuum electron and relates to a traveling-wave tube amplifier. A slow-wave structure is formed by periodically bending the double ridged waveguide (4) along the electric field to form a right-angled zigzag line or a U-shaped zigzag line; circular through holes are arranged at the positions along the mean axis symmetric line (2) of the slow-wave structure on the waveguide wall; and the slow-wave lines are connected by the metal tubes (3) with the aperture the same with that of the circular through holes between two circular through holes of the right-angled groove or U-shaped groove in each zigzag periodic structure of the slow-wave structure to form an electron stream channel.

A switched meander line structure is substituted for a lumped element antenna tuner for an order of magnitude increase in gain due to the use of the switched meander line architecture. The use of the meander line with relatively wide and thick folded legs markedly decreases I2R losses over wire inductors whose wire diameters at one-tenth of an inch contribute significantly to I2R losses. Additionally, placing solid state switches to short out various sections of a multi-leg meander line at high impedance nodes reduces I2R losses across the switching elements in the tuner.

The combination of a Vivaldi slot and a meander line loaded antenna is provided which exhibits an ultra wideband characteristic with the Vivaldi notch expanding the high end and with the meander line loaded antenna portion reducing the low frequency cut-off. When these antennas are arrayed, this array exhibits a single lobe and an ultra wide 100:1 bandwidth. The Vivaldi notch portion of the antenna accommodates the higher frequencies, whereas the meander line loaded antenna portion of the antenna accommodates the lower frequencies, there being a smooth transition region between the Vivaldi and meander line portions of the antenna and no discontinuity. In one embodiment, the antenna is made to work between 50 MHz and 1500 MHz with a VSWR less than 3:1. The Vivaldi notch meander line combination assures that for an array one does not have a separation of the elements more than a 0.5 wavelength at the highest frequency, thus to eliminate the possibility of creating grating lobes. As one goes down in frequency to {fraction (1 / 50)} of the highest frequency, the 0.5 wavelength is divided by 50. This means that antenna element spacing is 0.01 wavelength at the low frequency end, clearly below that separation which would cause grating lobes. In short, the generation of grating lobes at the high end is prevented because the antenna element spacing is less than a 0.5 wavelength, with the situation improving as one goes down in frequency.

A switched meander line structure is substituted for a lumped element coupler (10) for an order of magnitude increase in gain due to the use of the switched meander line architecture. The use of the meander line (20) with relatively wide and thick folded legs markedly decreases I2R losses over wire inductors whose wire diameters at one-tenth of an inch contribute significantly to I2R losses. Additionally, placing solid state switches to short out various sections of a multi-leg meander line at high impedance nodes reduces I2R losses across the switching elements in the coupler. It has been found that, regardless of the impedance of the antenna, this impedance may be matched by switching in and out various sections of a folded multileg meander line due to the fact that the square of the sum of the capacitive reactances of the meander line decreases with frequency in synchronism with the unloaded Q of the meander line, thus to provide the ability to maintain a good match over frequency as the meander line is tuned to achieve resonance by shorting out combinations of sections of the meander line. The result of the substitution of the meander line architecture for the lumped element coupler is the reduction of losses associated with the use of wire inductors and losses due to the interposition of solid state switches at high-current nodes.
