Abstract
In this paper, a compact L-shaped shorted pin patch to be used at local oscillator port in radar detector is proposed. Shorted pin patch operates as short-open cavity while conventional patch operates as open-open cavity. Shorted pins are L-shaped to obtain quarter wave length and three-quarter wave length resonance for the fundamental(X-band) and $2^{nd}(3^{rd})$(K- and Ka-band) mode resonance frequency, respectively. Thus, the proposed patch can be compact. It is also possible to operate at triple band(X-, K-, Ka-band) with small return loss in radar detector, It is expected that shorted pin patch could improve radar detector sensitivity.
