Abstract:
A novel design of a quarter-wave shorted trapezoidal metal plate solar
antenna using high efficiency polycrystalline silicon solar cells is presented.
Using the DC conductive parts of the cell as RF antenna
elements as well as choosing the radiating element to be a small
base trapezoid, better coupling between the feed and shorting plates
is ensured and 40.3% size reduction compared to a conventional
shorted quarter-wave patch is obtained. The trapezoidal radiating
element covers merely 2.7% of the total available illumination area
of the solar cell, leaving its efficiency essentially unaffected. The proposed
design strategy has been verified by an instantiation operating at
1.957 GHz and has a wide impedance bandwidth of 15.2% with a gain
of 4.5dBi.
