Antenna comprising two wideband notch regions on one coplanar substrate
First Claim
1. A broadband transmit/receive antenna, comprising:
- a substrate having a first face and a second face;
a conductive layer disposed on said first face forming a transmitting radiator portion including a first tapered notch and a receiving portion including a second tapered notch; and
first and second conductive lines formed on said second face forming first and second transmission lines, said first transmission line electrically coupled to said transmitting radiator portion at a first feed point and said second transmission line electrically coupled to said receiving portion at a second feed point.

Abstract
A broadband transmit/recieve antenna apparatus which operates at high frequencies and provides for two separate wideband tapered notch regions formed on one coplanar substrate. The tapered notch regions function as radiators for the transmission and reception of electromagnetic signals. The simple and compact design for the broadband antenna permits the transmission and reception of high frequency omnidirectional or directional radiation patterns. The broadband antenna interfaces with an an integrated circuit such as an ASIC which provides a series of pulsed signals and is resident on the antenna. The design of the broadband antenna provides for an optional stop notch to separate the transmitting portion of the antenna from the receiving portion of the antenna. Additionally, the antenna provides for impedance matching by locating transmission lines at an appropriate location with respect to the tapered notch radiators.
