Due to the low efficiency of the developed rectenna and the problem of most of the power being reflected at the antennadiode interface, an impedance-matching network
consisting of a plane array of rods was employed for improving the efficiency.
It is hard to use an impedance-matching network
to satisfy the various radiating conditions at two frequencies.

It's straightforward to synthesize an L-C impedance-matching network
that has the same effect as a tuner.

An L-section impedance-matching network
consisting of variable-capacitor and fixed-inductance arrays (as shown in Figure 7) is inserted in the transmitter circuit to match the input impedance [Z'.sub.in] to the source impedance [Z.sub.S].
The termination resistor element, coaxial transmission line launch and impedance-matching network
are mounted in a rugged aluminum housing.
The proposed cross-type networkis based on a T-type impedance-matching network
. As indicated in Figure 1, this front-end network can be embedded in any broadband system or antenna and expanded from a single tunable band to a dual-band network.
