If two or more adjacent modes are well excited simultaneously, the bandwidth can be twice or more than that for the single resonance. 1 LOWERING THE Q As mentioned in Chapter 1, a microstrip patch antenna having a larger sphere suffers from a narrow bandwidth as the whole volume of the enclosing sphere is not utilized effectively. Therefore, a microstrip patch antenna can be considered as a high-Q circuit, so one way to alleviate the narrow bandwidth problem is to reduce the Q. Investigations have shown that the shape of a radiator affects the impedance bandwidth, even for the same maximum dimensions.
