Abstract

A balanced wideband (WB) planar inverted-F antenna (PIFA) integrated with a balanced WB bandpass filter (BPF) is presented in this letter. Due to circuit symmetry, the balanced patch PIFA does not need a grounded via hole for its shorting strip, rendering the PIFA easy to fabricate. The balanced WB BPF that is added in front of the balanced PIFA serves to improve the differential-mode (DM) passband selectivity and upper stopband rejection and meanwhile to increase the common-mode (CM) rejection. In terms of the passband selectivity defined by the ratio of 20-dB bandwidth to the 3-dB bandwidth in the DM return-loss response, the simulated WB filtering PIFA's selectivity is increased from 0.6 to 0.86 after the WB BPF is integrated. In addition, high CM suppression was observed with a maximum return loss of 2.37 dB within the DM passband.
