A density taper technique for low side lobe applications of hex array antennas

A density taper design procedure, which allocates the element positions in a hex array to reduce near-in sidelobe levels, is investigated. This procedure adjusts the element positions to simulate a Taylor amplitude distribution function. This technique can be used in single power amplifier design (for every element) of a transmit phased array with reduced co-channel interference. Since no attenuation of amplifier output power is required, this technique has higher power efficiency than the amplitude taper technique. The performance of this density taper technique is compared to that of a Taylor amplitude taper technique
