Abstract
A tightly integrated combined transmit and receive dual quadrifilar antenna is provided. The antenna comprises four helical transmit elements and four helical receive elements disposed about a common axis. A receiver front end includes an arrangement of two 90 degree hybrids which serve to effectively reject signals cross coupled from the transmit elements back into the receive elements, while still allowing the receiver to receive signals.
